Drilling a tank Question

[Ugla]

i have a 100 gal acrylic tank and considering drilling for a closed loop. My question is I need to drill for a 2" bulkhead about halfway down in the center. Can I safely do this without completely draining the whole tank? I'd like to only drain to below the level of drilling. Any thoughts?

can drain it halfway and use something to catch the debri. drill from the inside if you cant get behind it maybe.

Will drilling a partially full tank put too much stress on the hole while drilling?

I don't ant it to crack.

I would drain as much as you can, and drill slow with a nice and sharp hole saw. Don't worry about the shavings as they float, and you can scoop them out with the ole fish net trick! Take a few pics and have some fun.
