AquaDoc pH Up for Swimming Pools — 5lb, 10lb
Sodium carbonate pH increaser
Fast-dissolving sodium carbonate formula for raising low pH in residential pools. Low pH produces corrosively aggressive water that etches plaster, corrodes metal fittings, and causes skin and eye irritation even at correct sanitizer levels. Pre-dissolve before adding near the return jets, circulate for 20 minutes, and retest before adding more. Compatible with all pool types and sanitizer systems.
