NT Labs KH buffer up 1.5KG

NT Labs KH Buffer Up is recommended when there is a need to increase the carbonate hardness (KH) of pond water. Pond fish require a safe and stable pH to maintain optimal health. Over time, as pond water ages and fish waste along with other organic matter accumulates, it can deplete the carbonate hardness (KH) responsible for providing a safe and stable pH. Insufficient KH levels can lead to unstable water quality, a sudden drop in pH, and potential illness in fish.
