Calcium booster spa products

Extend the life of your SPA

Leisure Time's Calcium Booster brings the hardness of your water up to the right level and suppresses foaming caused by other products. Spa water with too low a hardness level can corrode your equipment and damage plastic surfaces. Maintaining proper calcium levels will extend the life of your spa to its maximum potential.

For ideal SPA water hardness level

The ideal hardness level for spa water is between 150 and 400 ppm. One tablespoon (15 ml) of Calcium Booster increases the hardness by 7.4 ppm per 1000 litres of water. Determine how many ml you need and turn on the jets before adding the product to the water. Run the filter system for 1 to 2 hours after adding the product. Then carry out a new measurement and repeat the procedure if necessary.
