Hey everyone. I have a three day weekend coming up and I have some major changes I would like to do to my tank. First off, I want to paint the back of my tank black. Can anyone tell me about this process? What paint to use, how to apply it cleanly, and how many coats? Also, I need to change my sand. I have this stupid Caribsea white sand that is way too fine. It goes up in clouds at the slightest stroke of a tail. What sort of sand would be good? I like lighter looking sand. I've heard pool filter sand is good. Any oppinions?
