about to drill my tank

[Edmonton Eskimo]

I am just about ready to drill my tank and I am wondering about something the guy at my lfs told me. I didn't want to drill the bottom of my tank because I didn't want to have to mess with the whole internal overflow thing. I want to drill the back of my tank about 3-4 inches down from the top but he tells me I won't get very strong drainage. Is this true?

That's what I did with mine..... I setup an overflow using a hole and a pipe on the side towards the top.....

and........ if the water ever drains past that point it will stop draining...

Also, check out what kind of tank you have. Most have tempered glass in the bottom which cannot be drilled without risking shattering the glass.
