Yes, I'm assuming perfect mixing to make my life easy. The overflow will

act
as a settling chamber as well, since the filter will be after the sump to
allow as much Crap to fall out of suspension before it reaches the
filter.

Altum also mentioned the complexity of the variables and in the end I'll
just have to try it. But I thought it made an interesting problem.

That sounds like a great way of installing this unit, I never used one
this way.

We'll see what I've forgotten in a few weeks. I'm going to install a couple
of float valves, one to shut of the water if it gets too high and one to
shut off the pump if the water gets too low.

I was going to add the water to the bottom and take the effluent off the
top. But NetMax suggested plumbing my overflow to the bottom and adding the
water to the top. I should get more crap sucked out the overflow that way.
I'm not sure how much it will help, but it sounds good in theory.
