Diana, I was re-thinking the returns - you had suggested placing them at either end pointing straight, to maximize surface agitation.

Will the long overflow weir not do a similar thing? Also, there will be agitation where the drains enter the sump. Still necessary to to have the returns creating surface agitation from both sides? (I am thinking one to agitate the surface, one to flow under the overflow box.)
