JBL REFILL TEST GH – Refill Reagent for Total Hardness (GH) Test in Freshwater Aquariums
JBL REFILL TEST GH is the official replacement reagent for JBL’s total hardness (GH) test kit, designed for freshwater aquariums. This refill allows you to continue using your existing GH test kit without buying a new full set, making it a cost-effective and sustainable solution for water quality monitoring.
Total hardness measures the combined concentration of calcium and magnesium ions in the water, an essential parameter for healthy fish, plants, and invertebrates. Regular GH testing is especially important when using reverse osmosis water, as it helps maintain proper mineral balance through controlled re-mineralization.
Using the refill is easy: simply replace the empty reagent bottle with the new one and continue testing as usual, adding drops to your water sample until the color changes to determine the GH value in °dGH.
