LARGE Sump ideas....

[Chaloupa]

Everyone with a LARGE tank and LARGE sump....I need ideas for my 300g....I want an exterior sump that is large and functional..but have no ideas. I have been over Melev's site many many times, have looked at stuff on the other sites...but figured I'd try here too. PLEASE..if you have a LARGE sump (ie 100g) could you post pics of yours, what you like about it and what you would change if you could do it again? I really appreciate it!
