Hey guys, I just found a 300g tank (72 x 36 x 26) for 600$ and jumped on it. Its a commercial grade tank, and couldn't have been build more sturdy. Has a few scratches, but I don't think the fish will mind.

Anyway, Im going to be going the wet dry route, making the best of it's dual overflows. Problem is, I have never used a sump before. I'll have a pro helping me with setup, but want to lay some groundwork.

Anyone have advice or recommended reading you can point me to? What size sump should I be looking at? Any recommended brands? Is diy advisable? What am I getting myself into here?
