The pH value will affect 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 the undesired effects of quality issues and balance problems. Firstly these values should be checked at least once per week and more often after a fresh fill. Secondly it is 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. This can lead to turbidity in the water. SpaTime offers you an unbeatable product range that ensures an ideal water equilibrium and hardness stabilisation.
