Here's an idea... a 10 gl display w/pc lighting and a large rubbermaid sump with a fuge and skimmer. Seems a 10 gl display with a 30 gl sump would give an awesome amount of water for better advantages as far as water and a greater amount of area for nutrient control. Auto top off should be cake... just an idea, though(rubbermaids are cheap, too).
There's nowhere else I'ld rather be... unless, of course, you're buying
