I think my clean-up crew may be understaffed....I have a 20 gallon tank w/live rock, two mushroom polyps, a feather duster, two damsels, 2 camelback shrimp, 4 snails (astrea I think), and 3 hermit crabs. I had the basic 15 watt lighting until last week when I went to a 65 watt power compact for the mushrooms. I'm getting some brown algae on my rock and a brown film on the sides of my tank. Also accumulating on my sand. Is this normal? I know I need a sandsifter of some time - maybe a goby and/or horseshoe crab? Any suggestions appreciated!
