dude, that is a sick idea, i can glue it into the rim, just under it, using maybe some black pvc, drill my holes in it, attach it to the return pump, i may just have to get a maxi jet 400 for this, but hell, i dont care LOL, and yeah, the sump will be turned sideways, i just did it that way in the drawing so u could see the whole idea easier LOL maybe even build, when i build the stand for the lights, kinda seal the whole thing off, so you can only see the tank from the front, and close it totally in with 1/4" sheets of something, stain it, and hide the whole thing
