I have the 150 model running on my 90G. I have mine installed vertically on the back wall, right next to the overflow (with flow pattern directed across the back wall and away from the overflow).
I would agree with Aaron; wait for the less powerful model. I can only set mine @ 40% power; otherwise, sand gets blown all over the place. Actually, I had to limit it to 30% at first; until the sand shifts 'settled' and enough biofilm redeveloped on the sand surface to hold it in place. Then I bumped it up to 40%.
Otherwise, I am very happy with my unit. I removed ALL other powerheads and circ pumps from the tank - it is that powerful. Now my tank has a very 'clean' look to it, without all those pumps and power cords in the tank. In fact, if you look quickly, you don't really see the black gyre pump against the black tank background - and you wonder where all that water flow is coming from...
I am getting better suspension of detritus using the single gyre than I was getting using (2) mp40s. As far as I can tell I have ZERO "dead spots" using just the single gyre. I really does move a ton of water.
I have read some reports on ReefCentral of people complaining of noise (a hum) when using the Gyre, but mine is dead quiet.
I have seen no negative effects from running the Gyre with either my corals or fish. I did reaarrange my rockwork to get it off the back wall to allow the gyre flow to go completely around the tank.
My only complaints?
First, the unit came out of the box preset to start up at 100% power. So when I first plugged it in, it ran so hard it came loose off the back wall, knocked down half my rockwork from all that water force, and shot water out of the tank (!) That is just DUMB. Almost no one is going to run this at 100% unless they have a very large tank. It should be preset at the minimum (10%) and then the user can adjust it up from there.
Second, the directions stink. Bad Chinese translation. For $300 each, they should have better directions. No excuse for that, either.
Third, the controller is actually very nice and user- friendly; except the indicators are simply raised black symbols against the black controller face - difficult to see unless you have bright room lighting. If the symbols were done in a contrasting color (like white or yellow) that would be better.
But still, overall, probably the best water mover I have ever used. IMO better than a similarly - priced Vortech or a Tunze circ pump. Simply because you don't need so many of them to get your whole tanks water flowing.
Clean looking, energy efficient, quiet, and moves a ton of water.
