Ideal for lowering pH in decorative concrete ponds where upward pH drifts are common. Pond Acid Buffer also helps dissolve some of the excess carbonates and bicarbonates in hard water, which helps effectively lower and stabilize pH. Since it uses no phosphate or phosphoric acid, it will not harm your pond's koi, goldfish, or other ornamental fish. For liner ponds that experience hard water conditions, use Acid Buffer in conjunction with Pond pH Buffer. 2 L treats approximately 1,000 gallons.
