Believe me I wish it had been something else, that anenome completed the look of my setup. Its a 75 with an overflow filtration system, protein skimmer in the sump running with the fuge, 3 power heads for circulation. Water perm. were always within desirable range and until the carpet reached that enormous size there were no problems. After I removed it i did a small, 15 gallon water change which really wasnt needed, but nothing different then my usaul route like when the carpet was in the tank. After its was removed within a day everything started opening back up and growing. Its been two months since I removed it and all the zoas and mushrooms have started to multiply again, and the leathers are all growing and extending nicely, so Im lead to believe the carpet was the issue.
