I picked up another 55 and want to paint the back but have not been happy with any backgrounds I have used. I was at the lfs the other day and they have the typical light blue painted back and sides. The tanks are very bright and I asked about the lighting they use. Just typical T8 bulbs. Of course all their sa's are juvies and not colored up yet so I'm wondering if anyone has this combo on their tank and if the light blue with a natural substrate will wash out the color, give a natural color or enhance the color. Im thinking that the light blue on the back and sides helps reflect the light back into the tank and make it brighter.
