Hey there.
I have lots of stuff that I need identified. Im gonna get em together and organized so they ca be presented in a professional manner.

But before I do that, my tank is about 2 1/2 monthes old. I have two types of live rock. Some African stuff and Fiji. There is a brown algae like coating that has grown on most of the surface areas, along with some fans and various hitchhikers.
I guess my question is: Should I clean off the brown crud and risk losing some of my beneficial life?
Thanks for the info
