Barrs GH Booster contains 3 parts calcium sulfate, 3 parts potassium sulfate and 1 part magnesium sulfate. This is an excellent water conditioner that slightly increases the pH of the water (makes it less acidic). One tablespoon or 16 grams will raise the GH of 20 gallons of water by 3 degrees or 1 meg/ liter. One of the problems with Seachem's Equilibrium (or any of Seachem's products) is that you pay to have it mixed with water and then you pay to have the water shipped to you. We at aquariumfertilizer.com think that if you have an aquarium, that you have plenty of water.
