Description

Low calcium hardness can lead to corrosion of spa components, foamy water, and surface damage. Leisure Time Calcium Booster simplifies maintaining optimal water balance by delivering a precise dose of hardness-increaser granules. Just test your spa water, add the required amount, and let the pump run. It blends seamlessly with your existing sanitizing system—whether you use chlorine, bromine, ozone, or biguanide—without interfering with their action. The formula is designed for hassle-free use so your spa stays protected and comfortable.

Pro Tip

Test calcium hardness weekly—if below 150 ppm, add booster. Use Leisure Time Test Strips for matching accuracy. Add while spa water circulates on high speed for proper distribution. Consider pairing with a scale control product to keep mineral buildup in check.

Installation Tips

Add chemical to circulating spa water, not directly in filter. Ensure pump circulates on high for at least 15 minutes after dosing. Keep chemicals stored dry and separately from other spa chemicals.
