Features

• The salts of calcium and magnesium are a major constitution of general hardness (GH) which is a very important element to certain plants. Plant lesions, like tip shrinkage, twisting of leaves, and abnormal development, always happen in low GH conditions. Knowing GH value is the key to a successful plant aquarium. The normal degree of general hardness (dGH) should be kept between 7~9°
• S.T. international GH Test can easily and accurately read the correct GH value in the shortest time. The S.T. international GH Buffer will easily raise GH and KH (carbonate hardness up simultaneously, and keep it at a safe and stable condition.
• Some fish, like African cichlid and guppy, prefer an environment with a higher GH. Only when their water quality is healthy, will they have brilliant colors and be able to breed. In water with low GH, they are weak, easily get sick, and can even die.
