How old is the tank? I ask this b/c you said earlier that "My nitrates are about 40 and my calcium is at 410. My nitrites are very low and so is my amonia." You shouldnt have any NH3/4 or No2 and your No3 is a little high. You just might be still cycling or your feeding way to much or your not cleaning your sponges, pads etc etc. _________ 9YR OLD 90G/55g custom sump/refug Mag18 Aquac 180skimmer 692w MH AC jr,yel&kole tang,midas&convict blenny,B&G chromies,Blk/yel fin chromie blackcap,nemo,neon goby,6line; Blastomussa Merleti,Acan ,BUBBLE,Torch,LTA, Acropora(2) Moon, assort zoas, yel& G star polyps, P&B ricordia, montiporas, cup&candy corals, xenias,B/G mush,flower ane(2), cherry red mussa, dusters,cleaning crew..  |
