I have two 1" durso's on my 210 and can get 2000gph thru them. I use a Danner Hy-Drive 3200 with about 60" head. I have 1-1/2" plumbing on the pressure side and split that to four 3/4" returns with 3/4" loc line wye nozzles so as to not cause any more head loss than necessary. To be safe I divert 250gph off to a planted refugium so as to not push the drains to their limit 24/7.
Before going to the Hy-Drive I used a Mag18 plus a Mag7 and had to close both drains about half way to quiet them down. Thus the reason for the larger pump.
