The Rx Clear® Calcium Booster will increase calcium hardness in water to prevent any stains or deterioration. This product reduces both weathering and bubbling of specific chemicals. Rx Clear® Calcium Booster is made from 100% Calcium Chloride. Add Rx Clear® Swimming Pool Calcium Booster when the calcium hardness reading in your pool drops below 150ppm. Raising calcium hardness helps prevent corrosion of metal and plaster surfaces. Also helps prevent foaming of certain chemicals.
Rx Clear® Calcium Plus helps stop corrosion of metal surfaces such as light fixtures, railings, ladders, screws, pool cover components, pool heater components, and metals in your pump or filter. Also prevents etching, pitting, and delamination of concrete, plaster, gunite, shotcrete, and fiberglass pools.
Rx Clear® Calcium Booster is needed when the water hardness levels decrease below 150ppm. The ideal range is 200 to 400 parts per million (ppm). Six lbs. per 10,000 gallons will raise the hardness level approximately 50 ppm. The minimum calcium hardness level is 150 ppm.
Do not add this product on the same day that either ph plus or alkalinity increaser has been added to the pool water. Add when water hardness levels drop below 150 ppm. Spread the product over the surface of the water while the pump is running. Do not pre dissolve this product.
