Making Chemical Adjustments

Chlorine

To increase: Unstabilized Granular or Liquid Chlorine

To Decrease: Dilute the pool water; keep the pool surface exposed to allow
burn off

Alkalinity

To increase: Alkajuster

To decrease: Dilute the pool water

pH

To increase: pH Up

To decrease: pH Down

Salt

To increase: Add salt

To decrease: Dilute the pool water

Copper/Iron

To increase: N/A

To decrease (if Stain Erase does not work):

• Dilute the pool water
• Stain and Scale Control
• Natural Chemistry Products

Bromine

To increase: Bromine tablets; Oxidizer

To decrease: Dilute the pool water
