I am officialy starting a new tank again. After getting rid of my 180 I am coming back with a rimless 57. Can't wait, will start hopefully this weekend. Just a few questions, what kind of sump/refudge could I use and skimmer. There is so many out there I know but I am limited in what I can use as a sump/refudge because of the dimensions of the series two stand, it will be setup as a reef. Thanks guys for any inputs!
