Mine is running and added a lot of flow running at 40%. I didn't like it as the only powerhead in the tank because it just made everything flow one way. So I put my mp10 and jebao rw4 on the opposite side of the gyre to make some turbulence and wave action. Now my softies and gsp sway back and forth.
I think the weakest part of the gyre is the controller. I found it hard to make waves in pulse mode. It's so much easier to make a wave going with my mp10 or jebao. No night mode so it's taking up an outlet on my apex.
