Ive been wanting to setup a reef tank for awhile, I decided to setup a FOWLR as my first tank. Ive been lurking here and doing a lot of reading as far as what to do. Im looking for a nice 50-75 gal tank on craigslist and on the market place here, budget is tight so I have to go used. I understand the running a sump would be the best, but since im going FOWLR I think I could get away with running a canister filter (which I already have, bought off my friend) and having a good ammount of live rock. Any tips you guys could give me for a FOWLR? thanks
