I think they make a wonderful couple. lol. My tank is 60X35X21 and I have one gyre 150 + mp40 on one side of the tank. Together they generate very random flow. I get small ripples across the tank like small waves. I couldn't believe they compliment each other so well. And it's very minimal look with no giant pumps obstructing my view. I am also able to place SPS corals anywhere in my tank. I think I have found the best flow solution for my tank until they come out with something better/newer.
Pulling another page out of your book kid. I like your style haha. I ordered mp40 and a 150 gyre For my new 120g. It has a center overflow I'm going to mount the gyre vertically on side wall of over flow hopefully create a circular motion around the tank.
