I was just wondering what the best way is to remove the purple coraline that builds up on the back wall of my 12gallon nano cube dx. its getting really bad and the entire wall is just about purple now..

I agree why remove it.

What if the question were rephrased to say "what is the best method for removing coraline algae in the corners of the front and side glasses... near the silicone?"
