All About the Product

Product description

Colombo PH- – For safely lowering the pH level in garden ponds

Colombo PH- reliably lowers the pH level in pond water and helps to create a stable and healthy pond environment. A stable pH level is particularly important for the health of koi and other pond fish.

For a stable biological balance in the pond, a sufficient carbonate hardness (KH) is also crucial. A KH value of about 6–10 °dH is ideal so that the pH level remains stable and no dangerous fluctuations occur.

Colombo PH- is suitable for koi and garden ponds and can be used specifically to lower the pH level gradually and improve water quality.
