I believe this is Coraline algae surrounding my walls but not positive, it ranges from greenish-yellow to purple. It has formed a rim around the front of my tank, but only on the bottom 2 inches or so. Whats the best way of removing this? Its a bow front so I'm not sure if a razor blade or something might work; a mag float does almost nothing. I also am curious as to why it forms on the other walls from top to bottom, but only a 2 inch rim on the front; something to do with the flow i would imagine but just seems odd. Thanks for the help I would like to get my tank looking good again.
