I would like to set up a refugium next to my 55 gal. I would have to set up a 10 gal. beside it, but the plumbing is what i dont understand. I live on a fixed income and need something simple.(also so I can understand it, o.k., I'm a moron when it comes to this stuff.) but anyway, my 10 gal. sits lower than the 55. can someone help me in a way even I could understand (and afford).
