My initial impression is WOW!
My tank is 80x20x20, peninsula. I mounted it on the far end from the overflow replacing an MP40. 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.

The unit comes with an extra set of paddles and cages as well as extra bushings. Apparently there are 2 different sets of paddles so you can mix and match different flow patterns but I have not investigated this and installed with the default configuration.


BTW I turned off my other 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... I'll keep it, at least until I get a second Gyre....

NOISE:
Nope, just a light hum. 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...

Magnet: I have 3/4" glass. The pump is holding on but is pretty loose. I am using a sticky cord holed to hold it in place like an MP40. Apparently the upgraded magnet for 3/4" + glass will be out in a few weeks.
I read on another forum that the magnet is waterproof and the Gyre can be mounted on an overflow but I would get confirmation on that.

Those are my initial thoughts. I do have some buyers remorse.... I should have ordered 2...

Good review. I'm going to be doing something similar but with 3 of them. I have a coast to coast overflow in a 7' long tank by 36" front to back and 30" tall. I'm going to evenly space 3 of them across the back wall of the tank below the overflow. I know 3 is a lot but I'll be able to dial them down and provide an even gyre throughout the entire tank. I'm interested to see what happens to food when I add it to the water like this. Wondering if the gyre is going to cause the food to find its way right into the overflow or if it will cycle it around the tank a bit first.

Are there pre-orders for 35W version?

Thanks

I thought about the possibility of mounting the Gyre on the overflow but then I thought about surface skimming. ideally we want the flow in our tanks to suspend detritus and direct it to the overflow for skimming. If one were to mount the Gyre under the overflow teeth I think it would push the detritus away from the teeth. The wall of water coming from the pump is quite significant. Maybe the thing to do would be have the one on the overflow set in reverse so that it sucks water toward the overflow instead of pushing away from it...
When I feed I shut down my return, my Gyre is opposite my overflow. I was playing around and added food right in front of it at 70% and I watched a few pieces travel all the way across to the overflow then come back again along the bottom quarter of the tank then get sucked into the Gyre and spat all the way across again....

I went and picked up my new and improved mount today (it was delivered last week to my studio). The pump is now DEAD SILENT. I wasn't able to run pulse mode past 50% before because of the ramping up and down. Now I can go %100 without a peep. (if my tank could stand it which it can not)

I am really impressed with the way Maxspect took care of us early adopters... totally classy!

Thanks again Bill!
