Freshwater Hardness Test Kit by Mars
This test kit measures general hardness (GH) and carbonate hardness (KH) in freshwater aquariums, helping to maintain a stable and natural environment for fish.
By detecting rapid pH shifts caused by low KH levels, the kit enables aquarists to identify potential stressors and adjust water parameters accordingly to replicate natural conditions.
| Parameter | Measurement Range | Units |
|---|---|---|
| General Hardness (GH) | 0 to 30 | dGH |
| Carbonate Hardness (KH) | 0 to 20 | dKH |
