The industry’s only liquid calcium hardness increaser. PoolFlow Protect gives you accurate, consistent calcium hardness with no dangerous heat, no sludge and no waiting, just measure and pour.
Price range: $44.95 through $79.95
Calcium hardness is one of the most overlooked parts of water balance, until it causes problems. Get it wrong and you risk corrosion, etched concrete and damaged grout. The trouble is that traditional calcium flakes are a hassle to work with: they generate dangerous heat as they dissolve, clump into sludge if they absorb moisture, and eat up your time.
PoolFlow Protect is the industry’s only liquid calcium hardness increaser, and it does away with all of that. Just measure and pour. No dangerous heat, no melted buckets, no waiting for solids to dissolve, just accurate, consistent calcium hardness every time.
Active ingredient: 100% Calcium Chloride
Suitable for: All pools and spas, including concrete, fibreglass and vinyl-lined.
