Blue Horizons Calcium Hardness Raiser 5kg - For increasing Calcium Hardness of Swimming Pool Water.
Calcium Hardness is the measurement of dissolved calcium in water. For swimming pools, calcium hardness should be maintained at a minimum of 200mg/I (ppm) and become part of your water balancing regime.
Low levels can harm the pool and its equipment, this is especially essential if you have a tiled swimming pool. If the calcium level is too low, the water will be corrosive and can eat into the grout between the tiles. This can lead to tiles popping off.
Test the calcium hardness level of the pool water and if it is below 200mg/I (ppm) use Blue Horizons Calcium Hardness Raiser to increase the level. When adjusting the Calcium hardness it is important to maintain the correct pH level to prevent calcium deposits forming.
Helps balance pool water and is part of the BOAST system
