I've had my 35 gallon up and running for about 4 months now. This brown hairy/slimy algae has been growing like mad on a few rocks and on the back glass (I scrape the other 3 sides). Is this just a normal part of the maturation process or should I try and get this under control? I've got a decent clean-up crew and the only things that seem to make a dent are the Astrea turbos. Please help......(sorry for the iphone pics)
