Hi folks, I've installed two Hydor Flos to 2 of the 6 outputs on my Closed Loop. They are poiniting straight down, about 1/2" below the water's surface.

Anyway, the problem is I can see lots of water bubbling out the wrong end of the unit. (It's being pushed out in the opposite direction as the main output.) It seems like a serious waste of flow.

But maybe it needs to have water escape through the back in order for the gears to work right? Any ideas? I'd like to try and diy a gasket to block it up and see if that increases flow out the front.

Thanks,
Jh
