back overflows

[estey]

I have a rear overlow on my custom Starphire 125gal. that I built myself. The back pane has a long U shape cut out along the top and a piece of black acrylic with teeth was siliconed to the back glass. I then siliconed a glass box to the back of the tank. At the bottom of the box 3 holes were drilled and I put in a durso in each hole. The tank is completly silent and you cannot see any overflow in the tank.

I'll post some pics tomorrow when my lights come back on.
Cheers,

Derek
