Blueline(Pan World) pumps for return.

Scott I know you said you were looking to get one of these for your return. I was looking at them also. The tank i'm getting is a 135g RR (dual overflow) tank with 1" drains and 3/4" returns. I'm still not sure what the overflows will handle on this tank. I posted on RC and got little to no feedback.
I was thinking that with the eductors and all the plumbing with the pump pushing two returns that the HD70 would be the way to go but someone on RC said they were using the 70 from a basement sump that had to push 10' to get to the tank and he had to throttle it back. With that in mind I don't want to flood the tank or cut back the pump so bad that it burns it out.
I guess the HD55 would be the way to go. I'm going to put an extra T from the return back into the sump, or fuge depending on setup, so if it is too much i'll pump some water back into the sump rather then cutting the flow back putting more stress on the pump.
Does this sound like the route to go? according to the head loss calculator on RC i'd be pushing about 800-900 gph with the 55. I'm still unsure as to how to figure the overflow/drain rate.
As for the closed loop. I plan on using that reefflo dart with 5 outputs(no eductors). I'm going to put it on a shelf behind the tank and this will cut 2 ft of head pressure. According to the head loss calculation i'll be pushing about 2000 gph with all the plumbing. Do you think 5 outputs is too much or not enough. I'll have 3 along the back and 2 on the sides similar to what Scott has done.
With this flow i'd be turning the tank over almost 20 times an hour depending on sump/fuge sizes.
