I want to paint the back of my tank black what kind of paint are you guys using and is there anything that needs to be done special then like painting a wall?
Not to be a party pooper, but you might want to reconsider painting the back if you plan to grow corals.
Jim Fatheree from TFH did a study a while back, it was in the magazine and presented at MACNA, and the UNPAINTED back of a tank reflects quite a bit of light back into the tank, due to the mirror (refracticve index) effect you see when you look at the back from the end panel.
Of course, you need to be able to keep the back clean to get this benefit.
