Product Information

Or, remove the cover from the hot tub to allow evaporation of the chemical (keep the spa filter running constantly).

The number of bathers, water hardness and other outside materials such as mud, grass, and leaves will all affect chemical requirements. Hot tubs are smaller than pools and are shared by more people, meaning a greater amount of contaminants are brought into the water. Not balancing the Total Alkalinity levels in your hot tub can cause a number of issues that can impact your spa experience. Hot tub chemical maintenance is an essential part of owning a Lay-Z-Spa and is necessary for clean and healthy bathing water. Storing chemicals requires careful attention to the product label instructions for each individual product.

Total Alkalinity and pH work hand‑in‑hand and if these two are not balanced the sanitizer (chlorine) will not work properly.

Despite showering we understand that these substances are still sometimes present and will react with the water resulting in foam being produced. The chemical dispenser slowly releases the mini-tablets into the water, making this a completely hassle-free way of treating your water even for the user with a busy schedule. Some products may be delivered straight to your door from one of our suppliers and these products will be labelled within the product description.Chlorine tablets are very cost effective and arguably the cheapest way to kill bacteria in a hot tub. Dip a ClearWater® Test Strip in the centre of your Lay‑Z‑Spa, remove and hold it still for 15 seconds. The large 200g tablets are mainly designed for swimming pools whilst the 20g tablets are for hot tubs and small splasher pools. This is a very effective way of preventing your spa water from looking dull and cloudy, due to the build-up of dead algae and debris that is too small to be trapped by your filter. 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.

As well as containing chlorine, which kills bacteria and other ghastly organisms by disinfecting water, the tablets also contain an algaecide and clarifier solution. In our detailed Hot Tub Chemicals Guide you can find out everything you need to know from recommended chemical dosage amounts to hot tub chemical how-to guides. Alternatively keep the dispenser aperture constant and vary the tablets inside to achieve 1-3 mg/l (ppm).

Empty water, clean hot tub inside and out, backwash the pump, replace filters and re-fill with fresh water.

Mini multifunctional tablets make chlorine levels slightly more difficult to measure since the chlorine is released slowly over time. To ensure safe use of your pool, maintain a free chlorine level of between 1-3ppm and a pH level between 7. Most Lay-Z-Spa owners will be well aware of the two recommended ways to add chlorine to your hot tub water: Clearwater multifunction tablets and Clearwater chlorine granules. Verdict: Multifunction tablets are a great hassle-free solution for regular hot tub users, however, if you often find yourself shock dosing your spa then chlorine granules may be more convenient. ClearWater Clarifier contains flocculants that bind small particles of debris and algae together making it easier for your Lay-Z-Spa’s filtration system to capture and keep the water clear.As a guide - a hot tub of 1,000 litres requires 18g to raise Total Alkalinity levels by 10ppm (parts per million).
