I've let this go for far too long and I'm trying to get my tank back in shape. This algae has been around for quite a while now, and I'm trying to determine exactly what it is so I can begin to eradicate it. Any help would be appreciated.
The rocks become coated with the brown film easily within 24 hours of scrubbing them. The underlying rock is pretty clean looking after scrubbing, however there is some green algae that is very difficult to remove by scrubbing. As you can see, the brown film is removed easily.
