I have a 55 gallon tank with a single bulb/ ballast on the top. I have a bulb now that works but my rock wall is red lava plus wood so water / tank color is very red. I was wondering if there is a bulb to down play those colors a little and pull out more of the blue of the water and color of the fish (cichlids) is there somewhere i can look at pictures of different bulb and how they effect the tanks?
