This 16 lb pack from Clorox Pool \u0026amp; Spa dissolves readily and is formulated to be simple to apply, whether you maintain a chlorine or saltwater pool. Use it after filling a pool, after heavy rain or splash events, or whenever a test shows alkalinity is below the recommended range.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this product help maintain pH balance?\u003c\/h3\u003e\n\u003cp\u003eRaising total alkalinity acts as a buffer that reduces how quickly pool pH changes. By correcting low alkalinity first, pH holds more steadily and you need fewer corrective treatments.

Properly balanced water is gentler on liners, heaters, and metal fittings.
