Your tank looks great, I love the idea of a plywood tank.
thank you very much.....using plywood is the only way I could afford a large tank,I have been looking into using the solar tubes like you used over your tank plus blue LEDs because I like the more blue look in my tank,if I like the way yours looks with the blue mesh,I may plan to rely fully on the sun for light,either way,using the 4x250w halides are killing me on power consumption
