Advice on Vortech MP40w Placement

[Proteus]

The placement will give you lots of flow putting a circular motion. But I found IMO. That they create alot of undertow grom suction side so moving a little farther away from glass may be a good idea

Thanks - do you mean just to move the pump on the overflow side closer to centre (left) or both?

Yes. Personally I would. But not straight across from each other

I used the center of my side pane of glass as a starting point and went from there. I now have one 40 3" towards the back and the other 3" towards the front. 1 is about 8" down from the top of the tank and the other 12". 4'x2'x2' 120 gallon tank. I also point the solid section of the wet side towards the top of the water to allow the flow to spread out.

Once you get them where they work best for you be sure to use the cord ties to secure the dry side from falling. They don't land softly if they come disconnected.

Thanks for this advice. I like the idea of one higher than the other.

Also, I didn't know it mattered how the wet side was rotated. I will have to experiment with that.

After some quick research it appears that the orientation of the wetside does matter. To stop a vortex from occuring, the solid section of the wetside should be facing up towards the top of the tank. This makes sense from a physics perspective (although I am no Sheldon Cooper!).
