Put a hole in the glass, so the bulkhead can be installed?!
I get this feeling that you haven't watched the video and you don't know what an overflow really does...
The overflow on the tank is there so any additional water that is pumped into the tank, will drain out the "OVERFLOW"
This water is what feeds the media and flows into the sump...the pump pumps the water up into the tank where it can overflow back into the media and sump...over and over again...there is no siphon to deal with if you use the Glass-Holes.com overflow...
Now that you have a little backround, watch the vid on their site...
