About this item
- 【SAFELY INCREASES CARBONATE HARDNESS】: 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.
- 【BOOSTS KH LEVELS IN YOUR POND】NT Labs KH – Buffer Up replenishes these essential minerals leading to a safe and stable environment.
- 【EASY TO USE】: To work out the required dosage for your pond, simply calculate the volume of your pond in litres (length x width x depth (in cm)/1000) or alternatively, use our Online Dosage Calculator. Dissolve the powder in a bucket of pond water before adding to the pond.
- 【USE IN CONJUNCTION WITH NT LABS TEST KITS】: Use NT Labs Hardness Test Kit to measure the KH of the pond water. Always keep the KH above 6 dKH for optimal water quality. KH – Buffer Up can also be used to provide additional carbonate hardness where tap water is naturally low in hardness minerals.
- 【 SUITABLE FOR ALL POND KEEPERS 】: The ease of use of Koi Care KH Buffer Up means it is perfect for use by beginners and seasoned pond keepers alike.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
