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
Important Notes About Chemical Ranges:
- Calcium Levels should be on the higher end in concrete pools
- Calcium Levels should be on the lower end in salt pools
- ALWAYS ADD THE CHEMICAL TO WATER, NEVER ADD THE WATER TO THE CHEMICAL!
