I've been using Red Sea's Mg test kit since I started reefing. I'm wondering how accurate it is, and if anyone has a suggestion on a Mg test kit to try? I just received back my 2nd Triton ICP test and have had low Mg in both cases. 1297ppm in November test, and 1253ppm in December test. HOWEVER, my Red Sea test reads 1450ppm. My Mg has ALWAYS tested hight with the Red Sea kit; and therefore, have never once dosed Mg into my tank. I'm onto my 2nd Mg test kit, so I'm thinking its Red Sea and not just a 'bad' kit.
