The Nutrafin Carbonate and General Hardness Test Kit is a simple, yet accurate way to measure Carbonate Hardness (KH) and General Hardness (GH) in fresh and salt water aquariums.

The Nutrafin KH/GH Test Kit includes:
The Nutrafin GH / KH Test kit is a liquid kit, which works by changing the colour of a water sample in relation to the GH / KH level. You simply need to compare the colour of the sample to the easy-to-read colour chart in order to determine the GH / KH level.
