I notice that the Herbie style drain seems to be popular, I think I'll do something like that with a third emergency emergency drain because I'm paranoid (and the turbo snails seem to take delight in ending up in the weirdest/most impossible places). I figure that if I use 1.5" tube instead of 1" I should be able to cope with pretty much anything that's likely to happen. I hope!

I guess now I've got what I'm building sorted I'll have to do some head scratching and work out exactly how to build it..

Still not looking forward to drilling holes in the glass though!

a glass shop would take a 1/2" off that for about 20 bucks.. I also recomend a external overflow but if you don't have the extra 4" behind your tank then you can't.

as for 1" pipe.. it is to small for what you want using a durso. I would go two 1.5" with a durso and a durso is still loud. people have been having luck with the herbie set up using 3, 1" pipes. a herbie will handle more flow for the same size pipe as it is a syphon set up not a gravity feed setup.
