| | Re: Quick sump return question
I also have one sump set up with a return jet. It is aimed down a bit and almost straight ahead toward the front glass. In your case, with 2 outlets I would think that aiming them at a bit of an angle left and right is good, and just enough below the surface so there are ripples is best. Too much surface movement is not good.
If you have other pumps (power heads, filters) make sure the combined actions do not cancel each other out.
