Swimming Pool and Hot Tub Chemical Guide
Help with the Pool & Spa Chemicals Sold at G&T's Original Warehouse
It is essential to keep your swimming pool, hot tub or spa water clean, as bacteria will rapidly multiply in water that has been left untreated. By caring for your swimming pool or spa with the correct chemicals, you will not only kill potentially dangerous bacteria and keep your water safe to swim in, but also prolong the life of your pool, spa, pump and filter.
Are you having problems with the water in your swimming pool or hot tub? If so check out the problem and the remedy in the table below:
Symptom | Cause | Remedy |
Green or cloudy water, or slippery sides | Algae | Shock dose with Chlorine (see start up dose) and add Algaecide. |
Too much chlorine | Overdose | Drain pool to minimum mark and re-fill with fresh water to maximum mark, this will help to dilute the excess chemical. Remove cover from pool to allow evaporation of the chemical (keep the pool filter running constantly). |
pH hard to control | Alkalinity too low or too high | After testing the pH level with Dip Test Strips you can use pH Plus or pH Minus to increase or decrease the pH. Please re-test the pool after a couple of hours and before use. |
Difficulty maintaining chlorine levels | Chlorine levels are fluctuating, the pool has been left and gone stagnant or other chemical levels are not correct | Use Dip Test Strips to check chemical levels everyday, the filter pump should be left on for a minimum of 4 hours a day when there is water in the pool. If chlorine levels are fluctuating, you will need to check other chemical levels are correct. If the pool is being used quite a lot you may need to increase the chlorine levels. If you are going away we would suggest emptying the pool and cleaning it so the water is not left to go stagnant. Do no refill until you return from your trip. |
Cloudy water | Poor chemical control or inadequate filtration | Clean pool or spa filter cartridge, check chemical levels with Dip Test Strips and adjust if necessary (chlorine/pH). If problem persists buy Water Clarifier to remove small particles. |
Rough pool edges or sides | Scale formation due to high calcium levels in water | Ensure pH levels are correct using Dip Test Strips and use Scale Remover. Clear and clean debris screens, pipework and check pool filter for build-up. You may need to descale the filter pump as well. |
Foaming | Detergent present from incorrect cleaning products or excessive algaecide use | Reduce water level and top up with fresh water. Avoid domestic household cleaners. Avoid using domestic household cleaners, washing detergent, sun lotion, make-up, moisturiser, hair products and fake tan. We would also recommend showering before using the pool. We would also recommend using Foam Remover. |
Test strip water quality dip test does not change colour | Too high chlorine leading to bleaching of indicator pads (over 15ppm chlorine) | Check expiry date on Pool Test Strips. Wait for chlorine level to drop and re-test (See overdose instructions). |
Getting Started with Adding Chemicals to Your Swimming Pool
Setting up a pool for the first time and new to chemicals? These easy‑to‑follow steps will have you swimming safely in clean water in next to no time.
As soon as the pool is filled with water, you need to apply a booster / commissioning (Shock Dose) of Stabilised Chlorine Granules. Shock dosing a pool eliminates bacteria and any other contaminants in order to make it a safe swimming environment.
The amount of chlorine required to shock dose your pool depends on the volume of water. Refer to the instructions and guidance on your chemical packaging for dosage.
Top Tip: A tablespoon holds approx. 15 grams of Stabilised Chlorine Granules.
Rough Guide: You need 50 grams of chlorine granules for a pool of 1000 gallons (4545 litres).
It is a combination of circulating water and the filter cartridge collecting debris along with good chemical water treatment that helps you maintain clear, clean and healthy pool water.
You should run your pool's circulation every day referring to your user manual for more detailed advice. As a guide to running circulation, you should aim to "turn" the full volume of pool water through the filter cartridge once per day. Typically in most splash pools, using standard equipment, this is 4 hours per day (that the pump should be turned on).
Using ClearWater Dip Tests you are able to quickly and accurately assess the condition of your pool water and make adjustments to chemical levels with the appropriate chemicals when necessary. Test daily when the pool is in use and twice weekly when the pool is not is use.
| Test | Ideal Reading |
| Free Chlorine | 1 - 3 ppm (parts per million) |
| pH | 7.2 - 7.6 |
| Total Alkalinity | 80 - 120 ppm (parts per million) |
By regularly testing the pool water you will soon learn how various activities like refilling, topping up, adding chemicals and general usage can affect various test readings.
Treating Your Pool Water with Chemicals
Pool water requires regular disinfection to keep it free from bacteria, some of which may be hazardous to health. ClearWater Stabilised Chlorine Granules are ideal for this and are quick‑dissolving and relatively pH neutral. They are easy to use, simply measure out the quantity you need for your pool's volume of water, dissolve in a jug of water and pour into the pool.
Quantity needed to increase pool chlorine level by just 1ppm:
| Pool Volume | Increase Chlorine Level By 1ppm |
| 1000 Gallons (4,545 Litres) | 9 grams |
| 2500 Gallons (11,364 Litres) | 23 grams |
Water should be tested before use and Free Chlorine levels should be 1 ‑ 3ppm (parts per million). When adding chlorine to the pool, we recommend aiming for 3 ppm to provide a useful "buffer" for fluctuating conditions such as bathing loads and hot weather. The rate of chlorine consumption can and does vary depending on different conditions and chlorine will be consumed even when there is no swimming (i.e. by sunlight or by algae). The only way to be sure that there is sufficient chlorine present in the pool water is to test regularly.
The pH level of your pool water is also important as it helps to ensure the pool water is comfortable for bathers and the water is neither too acidic or alkalinity. The ideal pH range for a pool is 7.2‑7.6.
- Pool water with a pH below 7 is acidic which can cause unpleasant smells, bather discomfort and corrode metals. Use ClearWater pH Plus to reduce it using the application instructions on the bottle.
- Pool water with a pH above 7 contains too much alkaline which can cause skin irritation, scale formation and reduce chlorine efficiency. Use ClearWater pH Minus to increase it using the application instructions on the bottle.
Algae are microscopic forms of plant life that can quickly multiply in ineffectively treated water conditions resulting in slippery sides and green or cloudy water. Using chlorine in your pool helps to prevent algae, but for extra protection you can use ClearWater Algaecide which is a highly effective way to eliminate it and prevent your pool from looking murky.
| Pool Volume | Initial Start-Up Dose | Weekly Dose |
| 1000 Gallons (4,545 Litres) | 50ml | 25ml |
| 2500 Gallons (11,364 Litres) | 125ml | 62ml |
Cleaning & Maintaining Your Pool
Periodic cleaning of the waterline, steps and equipment in your pool will not only make it look good, but will also optimise the use of your chemicals during the swimming season. Use a skimmer or net to collect any debris floating on the surface. It is a good idea to do this on a regular basis to prevent any debris from causing contamination to the water.
We recommend ClearWater Miracle Pads for general surface cleaning and ClearWater Scale and Stain Controller to help combat any tough stains. Avoid household cleaning products as they may contain phosphates that nurture algae growth or detergents which cause foam.
Working Out Your Pool Water Volume
Working out pool water volumes can be tricky when considering how much of the pool chemicals you need to add. On most pool instructions the typical measurement will be provided in US gallons. See the table below for a typical guide:
| Typical Pool Size (Diameter x Depth) | Volume (Gallons) | Volume (Litres) |
| 10ft x 30in | 800 UK (961 US) | 3639 |
| 12ft x 30in | 1183 UK (1421 US) | 5377 |
| 15ft x 36in | 2240 UK (2689 US) | 10,179 |
| 15ft x 42in | 2720 UK (3266 US) | 12,362 |
| 15ft x 48in | 3038 UK (3648 US) | 13,807 |
| 18ft x 42in | 4203 UK (5046 US) | 19,100 |
| 18ft x 48in | 4661 UK (5596 US) | 21,182 |
Spa & Hot Tub Chemicals Quick Start Guide
Setting up a spa or hot tub for the first time and new to chemicals? These easy‑to‑follow steps will have you relaxing in next to no time.
1. Shock Dose - After filling up with water and before using your spa for the first time, shock dosing (adding a larger than normal quantity of Chlorine) your hot tub or spa is necessary to eliminate any bacteria or harmful organisms. It will also help to extend the time until you have to replace the water (assuming you keep up with regular chemical maintenance).
Find out how to shock dose your hot tub further down this page.
2. Test Water After 24 Hours - After a shock dose, you need to wait 24 hours. Test the water using ClearWater Test Strips to make sure the Total Alkalinity, pH and Free Chlorine levels are balanced before using the hot tub. At this point, you may need to make adjustments to certain chemical levels.
3. Test Regularly and Adjust Levels When Necessary - In order to maintain clear, clean and healthy hot tub water, you should always make sure your chemical levels are balanced.
See below for some easy chemical maintenance steps or continue reading our hot tub chemical guide for more detailed explanations and dosage suggestions.
Keeping spa or hot tub chemical levels balanced results in clean healthy water and it is easy if you remember these 3 steps in this order.
1. Start with the Total Alkalinity and aim for a reading of 80‑120 ppm. If it's low, add an alkalinity increaser, if it is high use a pH reducer.
2. Next, address the pH levels and aim for a reading of 7.2‑7.6. If it is low use a pH increaser and if it is high use a pH reducer.
3. Finally, look at the Chlorine and aim for a reading of 3‑5ppm. Total Alkalinity and pH work hand‑in‑hand and if these two are not balanced the sanitiser (chlorine) will not work properly.
Please note: Allow at least 2 hours between adding each chemical type and only use the hot tub once Total Alkalinity, pH and chlorine are within the required ranges.
Daily, Weekly & Monthly Chemical Maintenance
Here is some guidance and recommendations on frequent and occasional chemical duties and hot tub maintenance.
You do not need to tend to your hot tub on a daily basis unless you are using it daily. As long as you have set it up correctly, given it a shock dose then balanced Total Alkalinity, pH and Free Chlorine; a heated, covered hot tub will be fine for a few days up to a whole week, or even longer, without needing any attention.
Test Chemical Levels before use
Before you want to use your hot tub, make sure hot tub chemicals are balanced to maintain clean and healthy water. If your chlorine, alkalinity or pH levels are not correct, please refer to our chemical How To guides below.
Shock Dose If Used Frequently
Hot tubs are smaller than pools and are shared by more people, meaning a greater amount of contaminants are brought into the water. As a result, it's recommended that you give a shock treatment to the water once a week during periods of heavy use. Find out how to do this in our Shock Dosing Guide below.
During periods of less heavy use, the hot tub may not need to be shocked as regularly but keep an eye on water quality. Clear water doesn't necessarily mean clean water.
Check Chlorine Tablets Dispenser
If you use any type of slow‑release chlorine tablets, check the floater to see if you need more before chlorine levels fall below recommended levels.
Scale Control (for Hard Water Areas)
Around 60% of UK households are in hard or very hard water areas. To avoid scale build‑up (which can impact water quality and pump components) use a weekly dose of ClearWater Scale & Stain Controller.
Clarifier
ClearWater Clarifier contains flocculants that bind small particles of debris and algae together making it easier for your hot tub's filtration system to capture and keep the water clear.
Surface Clean
It is a good idea to get into the habit of giving your hot tub a nice clean at least once a month. We have cleaning packs with tools, antibacterial sprays, and miracle pads or individual items as necessary.
Replace The Water
The frequency of water changes should reflect the degree of use of the hot tub, as well as the results of chemical testing. If chemical levels have fallen far outside the normal ranges, or if you experience a dramatic loss of water quality, it is recommended that the water is completely replaced and re‑treated and tested again before use.
Replacing Filter Cartridge
Ideally, filter cartridges should be removed and cleaned after every use. Every few weeks, or after periods of heavy use, hot tub filters should be replaced with new ones. Look for discolouration or stiffness. We recommend using ClearWater Cartridge Cleaner to clean your filter cartridge and extend its life.
How to clean your hot tub filter:
- Ensure your pump is switched off.
- Remove the complete filter housing from your hot tub.
- Unscrew the filter housing and remove the cartridge.
- Wash off the cartridge with a garden hose or cool tap water and leave to dry. Do not use any detergent or washing‑up liquid to clean the filter.
- Replace the filter with either a new or clean and dry one. Do not use a wet filter cartridge as this will not clean work effectively.
Foam Remover
We always recommend that you shower before entering your hot tub. This is to reduce residue from products such as shampoo, deodorant, washing detergent, sun lotion, moisturiser, make‑up, fake tan and natural body oils which can cause chemical imbalances. Despite showering we understand that these substances are still sometimes present and will react with the water resulting in foam being produced. In order to resolve, prevent and control this we would recommend that you add ClearWater Foam Remover to your hot tub.
Chemical Dosages & How-To-Guides
Get help with Shock Dosing your hot tub and advice on adjusting Chlorine, pH and Alkalinity levels.
Total Alkalinity (TA) is the measure of your hot tub water's ability to neutralise acids. Balanced Total Alkalinity helps control the pH levels and the correct level to aim for is between 80 and 120 parts per million (ppm).
How To Balance Total Alkalinity Levels
1. Dip a ClearWater Test Strip in the centre of your hot tub, remove and hold it still for 15 seconds.
2. Compare your dip test strip results to the colour chart on the packaging.
3. Total Alkalinity results:
For low TA levels below 80ppm you will need to use Total Alkalinity Increaser. The amount of TA + you need to add to your hot tub depends on the volume of water and how low your readings are. As a guide ‑ a hot tub of 1,000 litres requires 18g to raise Total Alkalinity levels by 10ppm (parts per million).
For high TA levels above 120ppm you will need to use pH Minus. The amount of pH decreaser you need to add to your hot tub depends on levels are and on the volume of water. Check the dosage rates on the back of the bottle and measure accordingly.
Problems Caused By Unbalanced Total Alkalinity Levels
Not balancing the Total Alkalinity levels in your hot tub can cause a number of issues that can impact your spa experience.
| High Total Alkalinity | Low Total Alkalinity |
| Scale build-up, cloudy water, clogged filters, weakened hardware and irregular pH levels | Scale build-up, green water, irregular pH levels and loss of water quality |
| Burning eyes and itchy skin | Corrosion of metal elements (i.e. pump) |
| Ineffective sanitiser | Burning eyes and itchy skin |
pH measures how acidic or alkaline your water is and the ideal range for hot tubs is between 7.2 and 7.6. Balanced pH is necessary for other chemicals to work properly and imbalanced pH levels can impact your hot tub components and cause skin irritation.
How To Balance pH Levels in your hot tub
1. Dip a ClearWater Test Strip in the centre of your hot tub, remove and hold it still for 15 seconds.
2. Compare your dip test strip results to the colour chart on the packaging.
3. pH results:
For low pH levels below 7.2 you will need to use pH Plus to help raise the pH levels and balance the water.
For high pH levels above 7.6, use pH Minus to help bring those levels back down into the recommended range.
The amount of pH increaser or decreaser you need to add to your hot tub depends on the volume of water and how low your readings are. Refer to the dosage information will be printed on the individual chemical bottles.
Problems Caused By Unbalanced pH Levels
Because pH measures how acidic or alkaline your water is, it is important to make sure your hot tub ph Levels are always balanced between 7.2 and 7.6 to avoid impacting your hot tub and your spa experience.
| High pH Readings | Low pH Readings |
| Skin and eye irritation | Dry, itchy skin and eye irritation |
| Cloudy or dull water and foam | Corrosion of hot tubs components |
| Scale formation | More frequent filter changes |
| Less effective sanitiser (chlorine) | Less effective sanitiser (chlorine) |
| Shorter filter runs | Impact on Total Alkalinity |
Chemical levels in your hot tub can be impacted by different causes and results vary with each situation. The number of bathers, water hardness and other outside materials such as mud, grass, and leaves will all affect chemical requirements. We would always advise you re‑test the water before using your hot tub.
Chlorine is a sanitiser that controls and prevents bacteria growth and is essential for the hot tub water to be clean and safe to use. The recommended Free Chlorine* level in a hot tub is 3‑5ppm (parts per million).
How To Balance Chlorine Levels
1. Dip a ClearWater Test Strip in the centre of your hot tub, remove and hold it still for 15 seconds.
2. Compare your chlorine results against the colour chart on the Dip Tests packaging.
3. Chlorine level results:
For low chlorine results below 3ppm you will need to add the appropriate amount of chlorine to restore the balance. Please see the instructions included on the Chlorine Granules or Multi-Function Chlorine Tablets packaging and view our Chlorine Dosage Recommendations table below. If the levels are very low we would suggest shock dosing the spa or using Fast Action Tablets.
For high chlorine levels above 5ppm, we would suggest you drain the hot tub to the minimum mark and re‑fill with fresh water to the maximum mark, this will help to dilute the excess chemical. Or, remove the cover from the hot tub to allow evaporation of the chemical (keep the spa filter running constantly).
Problems Caused By Unbalanced Chlorine Levels
It is important to get your hot tub Chlorine levels correct. Not enough Chlorine can result in unhygienic bathing conditions, whereas high Chlorine levels can cause irritated eyes or skin.
| High Chlorine Readings | Low Chlorine Readings |
| Poor sanitiser efficiency | Poor sanitiser efficiency |
| Damage to components | Cloudy water |
| Red itchy eyes and skin rash | Bacteria Growth |
| Unpleasant smell |

Please note: The table is only applicable to Clearwater Chemicals. Dosages are only approximate and the effect of chemicals on your water can vary each time you use them, depending on the exact amount of water in your hot tub, water type, water temperature, positioning of hot tub etc. Therefore it is essential to test the water every time before you use it.
*Free Chlorine refers to the amount of chlorine in your hot tub that is available to sanitise or disinfect the water, keeping it safe for users.
Shock dosing a hot tub is adding a larger quantity of sanitiser, such as Chlorine, to break down organic matter, get rid of bacteria and any contaminants in the water making it safe to use. A shock dose can also help with any loss of water clarity or quality.
We recommend shocking your hot tub before first use, anytime the water is replaced, after periods of heavy use, at signs of slime or algae or after a loss of clarity or water quality.
How To Shock Dose Your Hot Tub
You need Chlorine Granules to shock dose a hot tub. Chlorine tablets are slow releasing and only used to maintain the correct daily chlorine level.
1. Check the water capacity of your hot tub and measure the Chlorine Granules accordingly. The size of your hot tub will impact how much chlorine you need to add. Use the shock dose recommendations table below to see how much chlorine you need to add to your spa.
2. Dissolve the quantity of Chlorine Granules in a jug of warm water and pour into your hot tub. Activate the air jets for a few minutes to circulate the chemicals evenly throughout the water.
3. After shock dosing your hot tub, you will need to wait a minimum of 24 hours. Then, test the chlorine level with the dip test strips and make sure levels are 3‑5ppm. Add more Chlorine if necessary and balance all chemicals before using the hot tub.
Hot Tub Shock Dose Recommendations Table
| Water Capacity (Litres) | Grams Based on 20g Per 1000 Litres | Teaspoons (Approx. 5g Per Teaspoon) |

Dosages are only approximate and the effect of chemicals on your water can vary each time you use them, depending on the exact amount of water in your hot tub, water type, water temperature, positioning of hot tub etc. Therefore it is essential to test the water every time before you use it.
When Do I Need To Shock Dose My Hot Tub?
- When you first fill up with water
- At the first signs of algae or slime
- After periods of heavy usage
- After a loss of water clarity or quality
- After a long period without use
- When you re‑fill with fresh water
Can I Use Chlorine Tablets To Shock Dose My Hot Tub?
Tablets such as Clearwater Multi-Function Chlorine Tablets are only to be used for keeping your chlorine levels stable. Tablets are slow dissolving and will not have the same impact as granules.
I have added An Initial Dose Of Stabilised Chlorine To My Hot Tub, When Can I Use It?
You can use your hot tub when the chlorine level sits between 3‑5ppm. You should allow at least 24 hours for any treatment to the water to dissolve fully and be safe to use.
Chemical Handling & Storage
Ensuring yours and others' safety when handling chemicals is highly important as failure to do so could cause serious harm or a fatality. Please, therefore, read the below instructions carefully on how to correctly store and handle chemicals.
Read Instructions Thoroughly On Each Product Before Use
Never use unlabelled chemicals and please read the instructions before use. Avoid getting chemicals in eyes, on skin or on clothing. Avoid breathing vapours when opening a container. Avoid creation of dust. Never add water to the product. Always add product to large quantities of water. Use separate clean dry utensils for each chemical and clean after use. Do not add the product to any dispensing device containing residuals of other products.
Wear Protective Clothing
When you're ready to begin mixing your chemicals, you should handle them with chemical resistant gloves. The glove material has to be impermeable and resistant to the product / the substance / the preparation. It is also advised to wear tightly sealed goggles and appropriate protective clothing such as long sleeves, trousers, and closed‑toed shoes that fully protect your feet from spills. You should also wash your hands after handling chemicals.
Spillages & Disposal
In the event of spillage, clean up using clean receptacles and dispose of carefully. Do not add water to spilled materials. Do not use floor sweeping compounds to clean up spills. Sweep and scoop spilled material into clean, dedicated equipment.
Every attempt should be made to avoid mixing spilled material with other chemicals or debris when cleaning up. Do not attempt to reseal any contaminated drums. Do not transport wet or damp material.
Adding Or Pre-Dissolving Chemicals
Always pre‑dissolve chemicals in a clean, plastic container in a well‑ventilated area. When pre‑dissolving chemicals always add chemicals to water and not vice versa. Always add the chemicals to the water.
Never mix different chemicals in concentrated forms. This includes the kit products but also with other products like bleach or weedkillers – a dangerous reaction may occur.
Safety
Do not eat, drink or smoke when using this product. Have a First Aid Kit available for any accidents
If inhaled: Seek fresh air and keep at rest in a position comfortable for breathing.
If in eyes: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. If eye irritation persists: Get medical advice/attention.
If swallowed: Get medical advice/attention or call a poison centre.
Safe Storage
Store in a secure, cool and dry place. Chemicals must be kept well away from children and pets. Always keep chemicals in original packaging.
Avoid Exposure to Sunlight and Humidity
When considering where to store your chemicals, the best storage locations are areas out of direct sunlight. Chemicals react poorly when in contact with sunshine and heat and require a dark, cool environment to control for any potential reactions.
Make sure that any outdoor storage of chemicals is as far away from your hot tub as possible and in a dry, covered area. Humidity or even small amounts of water can cause chemical reactions that could lead to dangerous fumes.
Provide Plenty of Ventilation
Choose a location with ample ventilation for storing your chemicals. In areas with little airflow, dangerous fumes can quickly accumulate if chemicals do start to react. Ventilation is even more important when multiple chemicals are stored in close proximity to each other, as certain chemicals may create a hazardous reaction when combined.
Be Attentive to How You Store Different Chemicals
Refrain from stacking different chemicals on top of each other as this is not advised. Storing chemicals requires careful attention to the product label instructions for each individual product. Material Data Safety Sheets (MSDS) are available on every ClearWater product page and should be referenced with care. Keep in mind to never store oxidizers and acids close to each other.
Take care to never store any chemicals on the floor or above your head. This reduces the risk of items falling or spilling. In addition, avoid stacking liquid chemicals above powdered ones due to the risk of a hazardous reaction.
Keep Chemicals Away From Flammable Items
Outdoor storage areas for your hot tub chemicals should be situated away from anything flammable. Keep any petrol‑powered equipment, like your lawnmower, in a different location. The storage area should also be away from sources of heat, like an outdoor fire pit or BBQ.
Do Not Reuse or Switch Container
Reusing chemical containers or transferring chemicals to another container is never recommended as it can be hazardous. When storing your chemicals, always use the original containers with their labels clearly legible. Each container was designed for the specific storage requirements of the chemical it contains.
Even if you're handling the same type of chemical, mixing a new batch of a chemical with a leftover batch of the same chemical can lead to a reaction from the older residue, or create fumes.

ClearWater Chlorine Granules are a rapid dissolving essential sanitiser for pools and hot tubs and an easy way to maintain clean, healthy water. The granules produce free active chlorine, which kills bacteria and other potentially harmful organisms. They're perfect for shock dosing and are considered an essential item in every hot tub owner's tool kit. They are quick dissolving and relatively pH neutral. ClearWater Chlorine Granules are available in two sizes, a 1kg standard size tub or a value large 5kg container.
ClearWater TA Plus
Low Total Alkalinity may cause pool or spa water to be corrosive and the pH levels difficult to maintain. ClearWater TA Plus is used to increase the total alkalinity of the water in your pool or hot tub. If TA levels are too low, pH levels won't be balanced and you may experience a loss of water quality and corrosion of metal elements inside the pump. Although pH Plus will increase your TA, it does so less efficiently than TA Plus which has been designed to help keep your spa or pool water at its optimum level. It is important to monitor the pH level of your pool or spa water to ensure it is at the correct level. If it is too acidic then the chlorine treatment may not work effectively, the water may cause irritation to eyes and it may cause damage to your pool or hot tub. Suitable for use with any brand of pool or spa, TA Plus is required if the pH of your spa or pool water is below 7.2.
ClearWater pH Plus
Anything and everything that enters a hot tub or pool contains its own pH level which naturally alters the pH balance of the water. Contaminants can include falling leaves, trespassing bugs, dead skin, natural body oils, deodorants or moisturisers. ClearWater pH Plus, also known as 'pH increaser', is the best way to increase a hot tub or pool's pH levels if they have dropped below the recommended amount. The recommended pH balance is between 7.2 and 7.6. Incorrect pH levels can impact the water quality, imbalance other chemicals, and cause the water to give itchy skin and eyes. To avoid skin discomforts and enable the chlorine in your spa to work effectively, it's vital that acidity is monitored and controlled. If pH levels drop below 7.2 acidity increases and a pH increaser is needed.
ClearWater pH Minus
Anything and everything that enters a hot tub or pool contains its own pH level which naturally alters the pH balance of the water. Contaminants can include falling leaves, trespassing bugs, dead skin, natural body oils, deodorants or moisturisers. ClearWater pH Minus, also known as 'pH reducer', is the most simple and effective way to reduce the pH level of pool or hot water when it has surpassed the recommended level. The recommended pH balance is between 7.2 and 7.6. High pH levels can impact the water quality, imbalance other chemicals, lead to scale formation and cause skin and eye discomforts. When pH levels are above 7.6 alkalinity increases and a pH reducer is needed. pH minus can also be used to lower TA (Total Alkalinity) levels.
ClearWater Multi-Function 4-in-1 Chlorine Tablets
ClearWater Multi-Function Chlorine Tablets are an incredibly simple way to maintain clear and hygienic pool or hot tub water. These 4-in-1 chlorine tablets are designed for use with floating dispensers or the Lay‑Z‑Spa ChemConnect. They will slowly erode over a period of 3 to 5 days, depending on the amount of water flowing over them. As well as containing chlorine, which kills bacteria and other organisms by disinfecting water, the tablets also contain an algaecide solution that prevents the growth of algae. The multi-function tablets also contain a water clarifier. Some debris and particles that find their way into water, such as dead skin and algae, are too small to be trapped by the filter system. Clarifier contains flocculants, which bind particles together so that a filter can trap them, producing clean and sparkly water. The Chlorine Tablets are available in two sizes, a 1kg standard size tub or a value large 5kg container.
ClearWater Fast Action Chlorine Tablets
ClearWater Fast Action Tablets are highly concentrated, fast acting Chlorine Tablets suitable for shock dosing your swimming pool, Lay-Z-Spa or hot tub.
