I am setting up a 120G BB mixed tank, and need some advice on how to setup water circulation (thanks everyone again for your advice on skimmer). The return pump will only flow about 1000GPH. I am thinking about either go with close loop with OM 4 way or two 1" sea swirls, or no close loop but with two Tunze 6000 with multi-controller (I hate to think about the cost of this one
). What's your opinion on these choices? How much flow I should have for a mixed tank? Any one has one of these setup for sale for a good price?
