JBL Test Gh
Check the hardness of your aquarium water with the JBL Gh Test.
The concentration of calcium and magnesium determines the total hardness of the water.
Water hardness does not have an ideal value, since each type of fish has its own level of Gh in its own habitat. For this reason, it is important to know the measurement value of the hardness of your aquarium so that it is related to your fish.
- 1 bottle of liquid compound to measure Gh.
- Measuring and mixing test tube.
