I've had my 2.5 nano setup for about a month now and I have the Pc light on for about 9-10 hours a day, I have a Peppermint shrimp in the tank with a few blue legs. It seems that I have to clean the front glass every other day just to keep the green algae down. I have some macro algae and some red algae (from foster&smith) in the tank, small amounts which are growning well. I wanted to know what could I add to the tank to take care of the algae on the glass and the rock? I know snails do a good job but what about a sea cucumber/slug? something with some color?
