Notching glass for external overflow

[duncangweller]

I like that ghost over flow. Looks pretty sweet and an easy way to add an external overflow onto any tank

rather than notch have seen similar in idea to the Ghost OF (just holes, no notch).

Piece of glass about 5-6" wide, length the same as the tank for a coast to coast lip. Glass is siliconed at an angle, holes drilled through back glass (no bulkheads needed) and external overflow box constructed.
