boxless overflow?

[horrifier]

ya thats def a drawback of having it done on the back of the tank, but since the tank is not drilled at all its either drill the back wall or use and overflow box, and they take up more space than the plumbing if u drill it i think. i kno the box i have on my 55 makes it so i have to have my tank about 6inches from the wall, so if i can cut that down any its a huge plus for me

if you want to avoid drilling this overflow is low profile but takes a little work, decently quiet as long as you angle the back pipes so there isn't a drop .... http://www.monsterfishkeepers.com/forums/showthread.php?311243-DIY-Overflow-Ver-9999
