Calcium Hardness 25 lbs

Description

With all of the difficulties calcium can cause, your first instinct might be to try and remove it completely – but that would be a mistake. While high calcium levels can lead to cloudy water and scale, low levels of calcium aren’t any better.

Here’s why: Water naturally wants to be balanced – and if your swimming pool water doesn’t have enough calcium, the water will actually try to balance itself out by drawing calcium from, say, your plaster pool walls in order to satisfy its need for the mineral. If you’ve got a vinyl or fiberglass pool , the water will attack metal fittings and heat exchangers, causing corrosion that can destroy the fittings and cause pinhole leaks (plus, it’ll leave telltale stains on your pool surfaces).
