Being newer at keeping sps and having suffered a few losses from swings I find myself testing constantly! My wife probably thinks I am a little obsessed at this point but I cant seem to find a test kits for Calcium and Magnesium that are quick and accurate! For Alkalinity I really like the Hanna checker and for calcium I really enjoy the Elos kit but can anyone suggest a fast(er) and decently accurate kit for magnesium and maybe calcium too?
