Water issues may seem like a difficult task to resolve, but by using our Water Problem Solving Chart below you can easily identify the causes and remedy. Find out how to shock dose your hot tub or see our Shock Dosing How-to Guide further down this page.

Hot tubs are smaller than pools and are shared by more people, meaning a greater amount of contaminants are brought into the water.At this stage the water is unlikely to have much chlorine (if any),so to avoid algae and bacteria from the start add a “shock” or starter dose of ClearWater Stabilised Chlorine Granules.

Developed with Lay-Z-Spa in mind, the range of ClearWater® hot tub chemicals includes everything needed to make sure your Lay-Z-Spa's water stays safe, clean and clear. When you’re ready to begin mixing your chemicals, you should handle them with chemical resistant gloves. and Total Alkalinity levels should measure 80 – 100 ppm or 100 – 120 ppm, depending on the chemical solutions used to treat a pool. Chemical water treatment for hot tubs is essential regardless of how long or how often you plan to use the hot tub and this starter kit has everything you need to get started and keep up the water maintenance. After testing the PH with your dip test strips you can use the following chemicals to increase or decrease the PH.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. The granules produce free active chlorine, which kills bacteria and other potentially harmful organisms. 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.

Avoid using domestic household cleaners, washing detergent, sun lotion, make-up, moisturiser, hair products and fake tan. Clearwater pH Plus , also known as ‘pH increaser’ is the best way to increase pH levels that have dropped below the recommended level.Untested water can develop a chemical imbalance which may result in an unhygienic swimming environment or skin irritations.

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. Chemical levels in your hot tub can be impacted by different causes and results vary with each situation. 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.Or, remove the cover from the hot tub to allow evaporation of the chemical (keep the spa filter running constantly).
