Any glass shop will cut the pieces needed and they won't cost much at all.

Also, only flood issue would possibly be on a power outage IF the silicone let go. But let me tell you, where I live, I get 10-12 outages a year, some for hrs at a time. Never one did my tank have an issue. If you have a standpipe style drain in the overflow you won't drain the whole tank anyways..

ahah I love how you're half arguing with urself
