Have you considered a couple sea swirls on either the return or a closed loop to randomize a provide some flow to those dead spots? Might be a decent alternative to another "thing" on the side of the tank.
Yep, those are on my radar and may be my next major purchase. Will have to wait a little while though, as I recover from the rebuild.
But meanwhile I picked up a Tunze 6105 for the opposite end.
Couple observations...
1) It's large. Definitely stands out more than the Gyre. Or MP inside the tank.
2) Nothing but a thin disc on the outside of the tank. Much better than MP in this regard.
3) COMPLETELY silent. Major points over both MP and Gyre.
4) Build quality *appears* to be on par with MP's. Time will tell. Definitely feels better than the Gyre.
5) Running both at 100%, wide cage installed on the Tunze, using Larry's Reef Frenzy dropped in the tank as my scientific guide

, flow appears to be pretty equal in force/travel, but of course the Gyre is wider.
6) Engineering/Design of the Tunze is pretty slick, i.e. shock absorbers and "floating" magnetic mount. No wonder its so quiet.
7) Tunze (once my $14 cable arrives today) works with/programs seamlessly with my Profilux controller. No need for another control module or whole separate controller.
8) Another cable will allow the use of a battery backup of my choice.
So right now I have the Tunze running opposite the Gyre.
No regrets on my purchase at the moment.
I definitely feel like it was the right decisions to NOT buy another Gyre right now.
But I will be watching as the product evolves. They pretty much nailed it in the flow department, but its most of the other areas that need work in order to compete at the same level as other higher end pumps.
