Features:
CALCIUM PLUS
- Use Rx Clear® Swimming Pool Calcium Booster when the calcium hardness reading in your pool drops below 150 ppm. Raising calcium hardness helps prevent corrosion of metal and plaster surfaces. Also helps prevent the foaming of certain chemicals.
BE AWARE
- 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.
PREVENTS CORROSION
- 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
WATER CHEMISTRY
- One of the most important aspects of proper swimming pool care involves the maintenance of balanced water chemistry. When swimming pool chemicals are not at their ideal levels, swimmers can be at risk of contracting illnesses and suffering from skin irritation, the water can turn dull and cloudy, and pool or spa equipment, hoses, and surfaces can become damaged.
DOSAGE
- The ideal range is 200 to 400 parts per million (ppm). Six lbs. per 10,000 gallons will raise the hardness level by approximately 50 ppm. The minimum calcium hardness level is 150 ppm. Trust Rx Clear® as the most reliable leader in pool cleaner products and supplies.
Dosage Rate:
Approximately 6 lbs per 10,000 gallons of water to raise hardness level 50 ppm
