Cal-Rise helps prevent corrosion of metal parts in spa and hot tub filtration systems by safetly raising the calcium hardness in the water.

Cal-Rise is completely soluble and it is safe to use the spa immediately following application.  Simply broadcast Cal-Rise over the surface of the water as directed on the product label.

Add Plus pH when the pH level in spa/hot tub water is low.  Plus pH raises pH levels to prevent irritation to eyes and skin and damage to spa equipment.

Add pH Minus when the pH level in spa/hot tub water is high.  High pH levels lead to scale formation, cloudy water and may cause eye irritation.

Alka-Rise works effectively to raise total alkalinity in sp/hot tub water.  Low total alkalinity causes the pH level to wander, can lead to corrosive water and renders disinfectants ineffective.

Broadcast Alka-Rise over spa/hot tub water as directed on the product label.  Regular testing of alkalinity is particularly important when bromine is in use.
