gH Test - Sera

With the Sera gH Test, you can easily measure the total hardness of the aquarium water. Total hardness indicates how many dissolved minerals, such as calcium and magnesium, are present in the water. This value is important for the health of fish, shrimp, and plants, as each species has specific requirements for water hardness.

By regularly checking the gH value, you can better tailor the aquarium water to the natural habitat of your animals. According to MaJa Koi, the test is suitable for approximately 420 °dGH and the package contains 15 ml of test liquid. If the total hardness is too low, mineral supplementation can be used; if the total hardness is too high, mixing with reverse osmosis water can help.
