you should get a test kit for CA. you should keep your CA above 350 ppm. if growin corals 400-420 is better. i would not use additives until you have a test kit.Prismaco said:Hey Dough, you said something about making sure you have enough calcium. Is it bad if there is to much calcium ? Or to little ? Also on 37g, how often should liquid calcium be added. Once a week ?
AGH OMG MAN!what's with the giant red molar on your stand?
