I switched tanks from a 150 gallon to 180 gallon and our old tank had crushed coral and instead of using it we bought Aragonite sugar grade sand. Well my nitrates are off the chart and never had problem before. Also our large sebae anemone has shriveled up to half his size. I did a 50% water change and still reading off the charts. I think where I made a mistake is I just read that I should of put crushed coral in nylon and put in sand but now it is too late for that. I have 200 lbs live rock, corals, clown tang, yellow tang, purple firefish, clown goby, 2 nemos, two fire shrimp, and clean up crew. Nothing else seems to be affected. Is there anything else I can do? Or buy to get the sand through the process faster? Please help!!!!
