So I have Fritz calcium chloride and I’m needing to raise my calcium levels in my tank. There’s approximately 16 or 17 gallons of water volume. I want to increase my calcium by 20ppm. I have no clue how much to mix or how much to water to use when I mix it. First time having to dose go easy on me lol. I was getting by with just water changes but my corals are demanding more now. It says that one teaspoon in 10 gallons raises it 50ppm so what if I mix one teaspoon in a 1 gallon jug? And how much out of that jug do I even dose?
