Melinda fed the system a floating flake food which got sucked into the overflow as soon as she fed, so most of the "goo" went straight into the sump. That led to a bit of cloudiness, but since this is all just part of the test, I am quite fine with it, plus wait till you see the pics...I think the bit of cloudiness is about as clear as many of the tanks I see posted here.
There has not been a water change yet because I've been gone, we got 400" of rain, and that means yard wrok, so it'll have to wait.
Melinda did however remove the curtain from the filter media. She said it was releasing a LOT of tiny thread particles that made the tank look like a snow globe. So we have blue filter media in the trays (picture below).
I also added the pump-portion of an old Whisper 2-10i to get some tubulence in the 10 gallon and provide better water movement.
Here are the pics as of this morning...
