Building a new 29

[RyanJ]

I am going to drill my 29 gal. Anyone know how big of a hole I should drill? 1/2", 3/4", or 1"? Should I drill one or two holes? I'm planning on using a Mag 7 or 9 for the return with a sea swirl. Which one should I use?
Thanks,
Ryan

I'd go for a 1 1/2 inch bulkhead. I have a 1 inch bulkhead (which requires a much bigger hole than 1 inch), and its perfect for my Mag 2.

Oops, I should mention that a 1 inch would be fine if you are drilling the bottom, although a bigger drain wouldn't hurt. I drilled my hole in the back glass.
