BV,

Your bottom drain is doing a good job of mixing all of the water, so it
really doesn't matter whether you pump it off the bottom or run it over
the
top.

That's what I figured. Right now, I have a second pump sitting in about 10
inches of water, that I use to splash water in the VF for aeration. At some
point it will be waterfall pump. I've started using that to water plants.
