after doing almost everything to my tank to lower nitrates. i have narrowed it down to my crush coral bed. i think its retaining to much nitates. after multiple mass water changes. i can only put a small dent on lowering the nitrates. i currently sit at about 40 ppm. i just dont know what to do any more. i have a good skimmer. a fuge. and still have a problem. is there any one out there that can hook me up with some araganite. or sand
