Find soda ash to raise pH or acid to lower it, using a county pool dosing table.
How it works
Scales 0.2 pH per 10,000 gallons: 6 oz of soda ash up, 12 fl oz of 35% muriatic acid or 1 lb of dry acid down. Real results vary with alkalinity and starting pH.
Before you order
- Fix alkalinity before chasing pH.
- Add acid slowly near a return jet and let it circulate.
- Test again before adding a second dose.
Common questions
What pH should I keep?
A common range is 7.2 to 7.8, and many pool pros aim near 7.4.
Why does the table only cover steps of 0.2?
Doses are published per 0.2 pH. Larger changes are scaled and are less certain, so dose in steps.
