Finally decided to get a clam after having my tank established for about a year and a half. My friend has one in his 24 nano and says they suck up calcium. I drip about a teaspoon of kalk in a gallon of fresh twice a week, actually up until a month ago and my calcium is 400 as of today. What calcium level should I strive for, the clams looks healthy and was open all day today, but might have to change koralia position due to a lot of flow directly hitting it.
