Designed to raise and stabilize your pond's pH. The ideal product for raising pH in liner ponds or in areas with acid runoff problems. Adds carbonates and bicarbonates to your pond, giving it greater buffering capacity against acids from rain, runoff, or other sources. Increased buffering capacity helps keep your pH steadier and prevents your fish from being subjected to dangerous pH swings. Since it contains no phosphate, it is safe for koi, goldfish, and other ornamental fish. Buffers between 7.2 and 8.2, but preferentially around 7.4-7.6. 2 L treats approximately 1,000 gallons.
