Thanks a lot. I'm actually going to have the sump on a table at about the
same height as the main tank (albeit behind a wall), and I plan on using a
pump.. this was more to settle an argument I'm having with someone.. though
I still may end up using a canister filter... obviously shouldn't be a
problem in the setup I'm thinking of.
Thanks again!
Jon
