Vortechs are a great product and so are the gyre pumps. They both have great features. I was running 2 mp60 on my 300 gallon but was never truly happy with the flow. Don't get my wrong, 60s create a crazy amount of flow. The problem I was having was they were so close to my sps they were beating the s*** out of the corals causing them to loose color and when I would turn them down I would loose function of the controllability. But before I was asked to be a beta tester for the gyre pump I told Lindsey (@ReefBullet) that there was no way the gyre would work as great at as a mp60 at pushing water. She swore she would change my mind. And boy did she. Here's a video of 1 xf150 going heads up against 2 mp60s

The mp60s are turned to full power and so is the gyre. But even then when I was beta testing I didn't thing the gyre was all that great. I was ok and created good flow but it had a crappy controller. All it could do was pulse and constant. I told everyone that it wasn't an all in one pump where u could only have one of them and be done. I still believe this to this day. If u think that one gyre pump and no other pump in a tank is your answer to all your flow needs then your a fool. The pump is only good at doing one thing and that's make a gyre. I thing they're a great addition along the sides of vortechs or tunzes or even multiple gyre pumps. When the retail version was released they had a way better controller then the betas did. The new controller would allow the pump to spin in forward and reverse. There is no other aquarium pump out there that does this and make the gyre unique. This forward and reverse movement allows the pump to push water in both directions like so

This is alternating gyre mode.
So here's how I have my 300 peninsula setup. I took the 2 mp60's off completely and replaced them with 2 maxspect gyres. There both running on alternating gyre mode. One is attached to the overflow box vertical running a 80% the other is attached to the center brace and running a 40%.

The only flaw in the gyre pumps is still I the control or lack of control. Ecotech is light years ahead of maxspect on developing there controllers to do multiple functions.
