My fish and corals seem to be doing well I purchased some great purple and green rock from lfs and it is great but my other live rock about 8 months old seems to have algea or sedimant on it i cant get rid of it. I think i have great circulation 500 gph It looks like there is dust floating in my water. I have bio balls,sponge and poly pads under my drip tray also a skimmer any SUGGESTIONS
