JBL Test KH
Accurately measure carbonate hardness (KH) with the JBL test.
Magnesium with carbonic acid and calcium compounds create carbonate hardness. Its function is to avoid possible potential drops in PH, something very important because the fish suffer drastically from variations in PH.
The recommended value is between 5 and 10º dKH.
- Bottle with liquid test.
- Test tube to analyze the sample.
This test is valid for both fresh and salt water.
