Determining flow through sump?

Ok I need advice... I'm building this sump right here:
http://www.melevsreef.com/acrylics/s...p_model_j.html

Dimensions are not exact, but same shape and design..
Now the sump part thats in the front. Its going to be 5" wide, 13" tall, 25" long...

How would I calculate the max flow I can send through that narrow sump?

I don't want the water traveling through it so fast that its throwing water over the bubble traps or something when it should be cascading over.

I could change the bubble traps from 1" apart and raised to, 1.5" apart & raised, if we think that would help.

I was thinking a Mag 7 or 9.5

Minus head loss, the 7 would get me approx. 385GPH, while the 9 would get me approx. 637GPH.

The total volume, of the sump (not counting ref.) is about 20g-23g

And I did try a mag 24 which was 1092 gph... and it was rediculas.. it threw the water about 4" over the bubble traps and sounded like niagra falls.

I don't know what i was thinking....
