    Do you know what size bulkheads you'll be using? The hole size will depend on that.

    I guess that should have been the question is what size bulkheads to use. I was thinking 2 - 1 1/2 inch or 2 - 1 inch bulkheads. I looked up the return pump rating and its 1300gph.

    Thanks

    If I were you, I'd get my plumbing figured out first, thinking about return, fuge, etc. Then I would check at my LFS and see if they have the bulkheads there, or order them. THEN I would have the tank drilled by a pro. It would be a shame if it cracked while you did it. Glass is not easy to drill.

    1" drain, 3/4" return.
