to drill or not to drill

I think you'd be fine drilling it as long as they are on the side and not the bottom, but 4 holes might be a lot for a 20 long.

I'd drill 2 holes in the back, one on each side near the top, and build a DIY overflow. They are easy to make with a specimin container and a dremel, or llebcire posted a great design for one in another thread just last week.

If you drill holes near the bottom, you run the risk of draining your tank if there is a problem.

I know that in early 2008, you guys had a tank drilling meeting. Anyone care to post tips on tank drilling? I know that you need a diamond glass hole saw and that you need to keep the drilling process under water, but I'm sure that there are tips to drilling that would increase your odds for successfully drilling your tank without breaking it. Thanks!

i dont think the bottom is tempered so i would drill 1 in the bottom center close to back so you could put in a overflow box with a durso stand pipe.then drill 2 holes on the back towards the top one on each side then get a scwd http://www.saltwaterfish.com/site_1...arent_id=6  go 1in hole for drain 3/4 for returns. glass drill bits on ebay cheap may be a member that has some. you tube has video as other sites do also on drilling tanks.good luck post a build thread.
