The Regal 20 lb Calcium Increaser Pail is a fast-acting, granular water treatment formulated with 100% pure calcium chloride to effectively raise calcium hardness levels in your pool water. Maintaining proper hardness is essential for protecting your pool’s surfaces, plumbing, and equipment from corrosive damage, especially in plaster or concrete pools.

Low calcium hardness can lead to etching, staining, and corrosion, while balanced levels help extend the life of your pool system and promote a more comfortable swimming experience. Regal Calcium Increaser dissolves quickly when applied as directed and is safe for use in all pool types and finishes.

Key Benefits:

• Raises calcium hardness to recommended levels

• Helps prevent corrosion, scale, and staining

• Protects pool surfaces, liners, plumbing, and equipment

• 100% calcium chloride—metal-free, fast-dissolving

• Convenient 20 lb pail for residential or commercial use

Directions for Use:
Test your pool water and add the appropriate amount directly to water pre-diluted in a bucket. For most pools, 1.25 lb will raise hardness by 10 ppm in 10,000 gallons.

Maintain proper water balance and protect your investment with Regal Calcium Increaser.
