Helping a friend set up a standard 150, 72x18, but I have no experience with gyre style circulation pumps. Tank will have a 2000 gph return that will be split to 2 return lines and will be a mixed reef with mainly LPS but a few SPS and some zoas. I'm thinking that 2 of the ice cap 2k gyres with the new controller will be just fine but looking for advice on if we should go with 4k. Also can you run 1 4k and 1 2k on the same controller?
