I'm am planning on starting a FOWLR, with the intention of going to reef eventually. Just want to really get the hang of keeping my parameters in check before I move to reef. I can not however decide on what size tank. I know bigger is easier to keep parameter wise but it's really not feasible. I'm tossing around a 20 long, 29, or 40b, recently been leaning toward the 40b. I am kind of intimidated with the cost of a 55. I don't know! Lol, I'm an over analyzer too which seems like it can be a real double edged sword in this hobby! The main thing is I don't want to get overwhelmed early on and get discouraged.
