About Hot Tub Chemicals

We use chemicals to treat our Hot Tub water for a number of reasons. Hot Tub chemicals ensure clear water, which is free from bacteria and therefore safe to bathe. The right chemicals will also make sure the water is not irritating, and has no bad taste or smell. It's a Healthy and Safety guideline to treat our Hot Tub water with chemicals, and it will also protect our Hot Tub and related equipment from corrosion or erosion. Read more..

Safe Use of Hot Tub Chemicals

Never mix Hot Tub chemicals together. Always wear protective clothing and equipment when handling chemicals. Never drink, smoke or eat whilst using chemicals. Always add chemicals to water, never vice versa. Always store chemicals correctly - in a cool, dark, dry place, away from children. When adding Hot Tub chemicals, use one at a time.

Our Hot Tub Chemicals

Stabilised Chlorine Granules for Hot Tubs

When using chlorine for your Hot Tub, please use only Stabilised Chlorine Granules, as they are almost pH neutral. The ideal level in the water is between 3 and 5 ppm (mg/l). When dosing, it's best to add a small amount at a time, as correcting an over dosing is much more difficult than under dosing. Your santiser is the most important Hot Tub chemical in your arsenal, as it's the main line of defence against infections, viruses and bacteria. A low Chlorine reading will leave bathers vulnerable.

Non Chlorine Shock for Hot Tubs

Hot Tub Shock oxidises the water of your Hot Tub. It's generally recommended to shock water on a weekly basis with Non Chlorine Shock, which eliminates waste contaminates brought in by bathers. After heavy bathing a shock of the water is highly recommended. Using non-chlorine based shock will let you have almost uninterrupted Hot Tub use, and in some cases will return clarity to the water.

Alkalinity Increaser for Hot Tubs

Total Alkalinity (TA) is the measurement of dissolved minerals, alkalis and bi-carbonates in the water. Having the right TA is vital to your water quality, as it has an effect on pH stability, and a possibly scaling and staining of Hot Tub fabric. The ideal TA reading is 80-150ppm. Too low, and pH 'bounce' may occur, adding some Hot Tub Alkalinity Increaser will 'buffer' the water from pH changes.

pH Increaser and pH Reducer for Hot Tubs

The ideal pH reading for your Hot Tub water is 7.4-7.6 if your TA (see above) is correct, you will need to add either some Hot Tub pH Increaser, or Hot Tub pH Reducer, dependant on which way your water pH needs to be adjusted.

Scale Inhibitor for Hot Tubs

The minimum reading for Calcium in your Hot Tub water is 250ppm, anything lower than this level maybe cause damage to the internal fabric of your Hot Tub. In hard water areas, it's essential to use Hot Tub Scale Inhibitor, which should be added on first use of the Hot Tub, and then weekly thereafter to ensure mineral salts don't build up. This will help remove these unwanted minerals, and ensure water clarity and problem free Hot Tub use. Continued lack of treatment for hard water could result in pump, jets and internal pipework failure.

Spa Foam Reducer for Hot Tubs

Occasionally, your Hot Tub may experience excess foaming, which will generally be caused by detergents like Shower Gel or Shampoo. Even residual detergent from bathers can build up and cause Spa foam. A small application of Spa Foam Reducer will suppress this foam, but care must be taken as over using the Spa Foam Reducer will impact on water quality, filter efficiency and bather comfort.

Waterline Cleaner for Hot Tubs

Using a Hot Tub surface cleaner periodically is recommended to clean the waterline, but ensure you use it sparingly as overuse can promote foaming and water clarity problems. Use a clean cloth to apply our Waterline Cleaner , and a second clean cloth to remove the residue. Be sure to dispose of waterlogged cloth away from the Hot Tub water.

Hot Tub System Cleaner

A drain of your Hot Tub is recommended every 16 weeks, and should be accompanied by a system flush treatment prior to draining. Our Hot Tub System Cleaner will give the internal pipework and components of your Hot Tub a complete cleanse, a process which should already be standard industry practice in our opinion. Filters should be removed before Hot Tub System Cleaner
