Koi Care Pond Buffer increases buffer capacity, stabilises PH. 3 KG Treats 4500 Gallons

The buffer capacity of pond water is the ability of pond water to maintain the pH at the correct level for the survival of your fish. The metabolism of fish in the pond tends to use up KH buffer and if this is not replaced can lead to sudden pH crash causing death of fish, frequently at night. It is advised to test KH regularly with Pondlab Hardness Test Kit and maintain the KH level above 6 degrees carbonate hardness.
