To prevent calcium precipitations.

SpaTime Hardness Stabiliser

SpaTime Hardness Stabiliser helps prevent calcium precipitations forming on parts of the hot tub. If calcium deposits are allowed to build up on components of your hot tub it can severely affect its performance. Heater failure can be caused when excessive calcium build up on the heating element.

Test your source water before filling the Hot Tub with InstaTest 4 way test strips

Well being is also about the right water quality and the right balance. The pH value which affects the longevity of your spa,  the efficacy of the water care products and your well-being should be maintained between 7.2 – 7.6. Total alkalinity (TA) contributes towards the water quality and balance and should be checked regularly. To avoid undesired effects, quality issues and balance problems these values should be checked at least once per week and more often after a fresh fill. It is also important to note that the warm water of the spa tends to naturally  increase the level of the pH and can result in calcium precipitations leading to turbidity in the water.

SpaTime offers you an unbeatable product range that ensures an ideal water equilibrium and hardness stabilisation.
