To raise the total alkalinity (TA)

SpaTime Alca Plus

SpaTime Alca Plus raises the total alkalinity (TA) of your spa water.

Well-being with well-maintained water.

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.



SpaTime Alca Plus raises the total alkalinity (TA) level of your spa water. A low TA level may cause the pH to fluctuate. It also causes spa water to be corrosive, which may result in staining and damage to the spa surfaces.

if the total alkalinity is high use SpaTime pH Minus  to reduce your TA levels.


• Prevents spa and equipment damage

• More stable pH value

• Improves flocculation
