Calcium Problems!
Hi, just some info… i have a 75 gallon tank 20g sump, octopus skimmer 90 or so lbs of fiji live rock and no corals. I have a feather duster multiple snails and crabs, a clown fish and a money plant (Halimeda? if that’s how you spell it). I do weekly water changes using natural sea water, with calcium of 340 ppm. I have been adding liquid calcium (kent) and i cant seem to get the calcium up over 360ppm. I have two different brands of test kits to back this up. Please tell me what i am doing wrong!
