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.

Bottom of pond has most bad stuff.

I have a bottom drain, so is it safe to assume I am circulating the bad
stuff? Can I just drain from the top?
