Blue Horizons Calcium Hardness Increaser is the perfect choice when it comes to raising your calcium hardness levels. If your calcium levels are too low this will mean that your pool water will be calcium hungry and try to take its calcium from grout and other cementious material ruining your pool. Idealy for tiled pools you want to maintain your levels between 250 mg/l (ppm) and 1,000 mg/l, but don't let this get too high or you will find that scale will build up. This is our favourite brand due to its high quality and lower price, you can be sure that by choosing Blue Horizons you have made a good choice.
