AquaDoc Pool Alkalinity Increaser — 5lb, 10lb

Sodium bicarbonate-based alkalinity increaser for raising total alkalinity in pools below the 80 ppm threshold. The mandatory first correction in every pool chemistry balancing sequence — stabilizing alkalinity is what makes every subsequent pH and sanitizer correction hold rather than drifting back out of range within days. Pre-dissolve before adding, dose in increments, retest before proceeding. Compatible with all pool types and all sanitizer systems.
