There is some green bubble algae as well as a coat of what I can best describe as looking like green dust algae. This rock/coral came from a tank I bought. It has a lot of things I would like to keep out of my tank. While I can surely clean off the rock, I was hoping to go with a new piece of base rock to minimize the risk of bringing new things into my tank.
It seems that everything I read says that this is not easily done.... I was just hoping some of you have had better results.
