Just got the new gyre xf150. I'm more than impressed. For those that haven't seen my old threads or know me, I have a 180G RR tank. I did have 2 mp40's in the tank. I did some research and also saw it at MACNA, but I bought a gyre xf150 from Coral Xpression. I took video of both pumps to show my point and allow others to see it as well and develop their own opinions. I, for one, am impressed. I'm still playing with the pump and figuring it out, but I will post the videos and let you see.
