Colombo KH Test
Colombo KH Test –
For testing your KH value in the pond. A correct carbonate hardness (KH) is a precondition for clear pond water, healthy plants and fish and a stable acidity (pH).
KH is a value that represents the total amount of dissolved carbonates in your pond. If the KH is too low, the pH value can show rapid fluctuations, which is very harmful to pond life.
If your pond has a GH or KH value that is too low, you should first use Colombo GH+ and/or KH+ to bring it to the right level.
The package contains 25 sets.
- Accurately measures KH in pond water.
- 100% Synthetic.
- All Life Stages.
Note: It is wise to test at least 2 x a week for the first time. Then you should check the values of PH, GH, KH NO2, NO3 and NH3 monthly.
