I don't have strainers, but I don't have snails. Maybe I'm playing with fire. Just something to think about. If you cover the top of the overflow with mesh or something, that might be sufficient too.

I think the argument to playing with fire is that that's the purpose of the emergency drain. But then again you don't want to have to actually use it. As far as the depth I guess I'll keep it there and drop by an inch untill I find the sweet spot. The first article I ever read about herbie over flows suggested 6". So I'm sure that's where I'll end up. This thing is in the bedroom so we certainly want quiet.
