No sump. Just goin with the HOB protein skimmer and LR.
I'm definitely going with a majority of invertebrates for my reef. The fish are ok, but its the crabs, slugs, starfish, urchins, etc., that tinkle my fancy.
I also wasn't going to do much rockscaping... but then I made the mistake of browsing the forums here and saw how it looks with a good scape. So now, I'll be rockscaping.
This one definitely caught my eye.
