Robelle Pool Stabilizer and Pool Mate Calcium Hardness Increaser for Pools, 12 and 25-Pounds

The Robelle pool stabilizer and Pool Mate calcium hardness increaser bundle provides two complementary pool chemicals to help maintain proper water chemistry. The Robelle stabilizer contains cyanuric acid to help reduce chlorine loss from sunlight exposure, while the Pool Mate calcium hardness increaser prevents corrosion, staining, and etching by increasing calcium levels.

By stabilizing chlorine levels, less chlorine needs to be added, resulting in cost savings. Use 6 ounces per 5,000 gallons to raise cyanuric acid 10 ppm, and maintain 40-100 ppm for optimal efficiency. Add 8 ounces of the Pool Mate per 5,000 gallons to raise hardness 10 ppm, and keep calcium between 200-400 ppm depending on your pool type. Low calcium causes water balance issues.

Using both chemicals provides better chlorine stabilization and optimized calcium hardness for crystal clear pool water. The Robelle stabilizer reduces chlorine consumption by up to 25% while the Pool Mate protects pool surfaces. Together, they complement each other for easier pool maintenance.

Cyanuric acid stabilizes chlorine and extends its effectiveness against UV rays, leading to up to 25% chlorine savings. Calcium chloride, on the other hand, prevents pool surface corrosion and etching while providing water balance.

Maintaining the recommended stabilizer level of 40-100 ppm and calcium hardness of 200-400 ppm is crucial. The convenient dry granular formulas of both products dissolve rapidly for quick stabilization.

Regular testing with a reliable test kit determines optimal stabilizer and hardness levels, ensuring the proper balance of chemicals for a crystal clear and well-maintained pool.
