Why customers choose PatioZora Garden

Keep your pool surface protected and equipment running smoothly with Pool Mate 32-Pounds Premium Calcium Hardness Increaser. This dry granular formula raises calcium hardness to the target range, supporting a balanced water environment.

Why calcium hardness matters

Calcium hardness helps protect pool surfaces and components by reducing corrosion and etching when the water balance is right. Choose the appropriate target range by pool type: Vinyl pools 200-300 ppm; Tile and exposed aggregate 200-400 ppm; Marcite, fiberglass or painted pools 250-400 ppm. If tests show hardness is below the range, follow the included dosing guidance to raise levels gradually.

  • Calcium chloride for pools
  • Rapidly increases total hardness
  • Helps prevent corrosion or etching of pools
  • Ideal calcium hardness range 200-400 ppm
  • 8 ounces raises calcium hardness level 10 ppm per 5,000 gallons
  • Prevents staining or etching of pool surfaces
  • Low calcium hardness can cause water balance issues

How to use

Test the water with a reliable kit to determine current calcium hardness. Mix up to 2 pounds of Pool Mate per approximately 5 gallons of pool water in a plastic bucket. Slowly pour the solution around the pool perimeter while the circulation system runs. For a 10,000 gallon pool, do not exceed 10 pounds per 2 hours.

What to expect

Expect a gradual adjustment toward the target range. Maintaining proper hardness can help protect surfaces, support stable chemistry, and reduce the risk of surface wear over time. Results vary with pool type, size, and existing water balance, so monitor levels and re-test as needed.
