Product Description

Correct balance of chemical factors such as total alkalinity, pH and calcium, is needed for your sanitiser to work effectively and efficiently, the water to be pleasant to swim in, and to prevent scaling or corrosion of the pool surface and equipment.

Low calcium may cause foaming and leaching of calcium from pool surface and equipment causing unsightly damage.  High levels may cause damaging calcium deposits on pool walls, and in plumbing equipment which will reduce water flow.  May also clog filters.

Test Monthly with Test Strips/Reagent tablet – Range 0-500, although preferred range is 150-300

Reduction
