The tank is doing great! I now have my flow all sorted out. I was leaning heavily on 1 MP40 and several MJ 1200+900s while waiting patiently for the Maxspect Gyre to be released. It caught my eye several months ago in a MACNA video and I knew it would be perfect for my a long peninsula tank.
I finally got it and installed it a couple of days ago and WOW!
I mounted it on the far end from the overflow I started at %50 in the default A-B Paddle combination.
With no other pumps running this thing is easily providing enough flow at %50 for the whole tank. Detritus is being kicked up from all over the place and is being suspended and is moving back towards the Gyre then it is being spit back towards the overflow meaning the flow is ricocheting off the far end (as advertised) and there is defiantly a Gyre effect in the tank.
There are 4 modes to run it in
1. Constant speed - this provides a sheet of water that creates turbulence across the surface of my whole 80 inches at %50.
2. Pulse. You can set it to pulse at intervals from .4s to 30 seconds. there are 20 pulse time options here.
3. Alternating Gyre mode. - This is where it gets interesting!
The pump can can switch directions, spinning opposite has less power than forward because of the paddle design but you can set it to compensate for example 50% forward and 100% reverse. You can set it to switch directions from 2 minutes to 12 hours with 10 intervals in between. I have set mine to 50% forward, 100% reverse switching every 15 minutes.
4. 1 button 10 minute feed mode
The controller is very easy to use and looks good. Apparently 3rd party controllability is in the works.
I turned off the MP40 at the opposite end of the tank when I first set up the Gyre. I don't think I'll need to turn it back on... But I will, I am going to keep it and run it on ReefCrest to provide random counter flow... or I may sell the MP40 and get a second Gyre... ya that's probably what I will eventually do but I will wait for the smaller 35 watt version.
The Gyre is very quite. Running at %50 constant the hum is less audible than the hum of a properly seated MP40 on constant (green) at %50. Sitting here typing I can't even hear the Gyre anymore under the hum of my Eheim 1262 return pump. I could hear it at first because I was trying...
Here's some photos:

New Hippo tang- My wife absolutely loves this fish
Forest Fire and Bird of Paradise colonies from my old tank...
New Flame Hawk- i lost my old one in the move- I absolutely love
this fish
Clown and Anemone - notice the tentacles of the anemone are pointing away from the overflow. That means that the flow from the Gyre goes all the way across the top, hits the wall with the overflow and come round the bottom with enough strength to push the tentacles of the anemone which is situated in the 3rd quarter of the tank back towards the Gyre. The flow actually comes all the way around the 80 inches.
