When to use?
Pond fish require a safe and stable pH to remain healthy. As pond water ages, fish waste and other organic matter uses up the carbonate hardness (KH) that provides this safe and stable pH. If left unchecked, a low KH can lead to unstable water quality, a sudden drop in pH and serious illness in fish.
NT Labs KH – Buffer Up replenishes these essential minerals leading to a safe and stable environment.
How to use?
Q: Does your KH buffer contain phosphates? A: No, our KH buffer products are both phosphate and nitrate free.
