I have a 29 b.c. my water par. appear to be close and everything is thriving in the tank. However cant seem to get rid of this brown film on the surface of the water i do about 3-4 gallon water change a week seems small but have alot of live rock with coral so about right for water volume. I had the b.c. skimmer but it broke and really was junk anyway. I have been skimming it off during water change but does little to help and when i do this stuff just sticks all over your hands and arm im guessing some type algae. Oh ya been running carbon alot too. Anyway i appreciate any help anyone can offer me thanks again.
