I want to set up a small ref like a 40gal or less i have a 29gal and a 20gal L and a 10gal, but i'm torn about what to set up and how to set it up to be able to do the most with it, i would like to make a sump and go that route but being I'm in a dorm id like to stay away from it for time being to er on the side of caution even though I've already okayed things i just don't wanna push the envelope. whats best set up please help me guys I'm here at home on leave and would like to take all that i need with me vs having to buy it when i get back to my duty station!
