NT labs KH Buffer Up 1.5kg


Stabilises pH


Maintains healthy water conditions.


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. 

Test your water quality first using Pondlab test kits.
