stsGHKH is an utility that calculates water hardness of a water planted tank or a marine tank. It supports the calculations of both general hardness(GH) and carbonate hardness(KH). GH and KH are important parameters for keeping a water planted tank or a marine tank in good health. This app has the folloing features:
• Generate a list of water hardness needed to be added because of water change;
• Ability to set the desired level of GH and KH;
• Ability to set the hardness mixture strength for both GH and KH;
• Define the tank size to support;
