I found a great deal on 2 saltwater tanks that are up and running and I cant pass it up. It comes with a 120g tank with 55g sump and a 90g with a 35g sump. Oh yea and everything else such as powerheads lights skimmers return pumps all of it. Dont forget the 200lbs of live rock and a few fish. Though I have had multiple saltwater tanks before from 5-220g i am nervous because i have been out of the hobby for a few years due to moving and feel like 2 tanks may be a lot to jump back in with.
