Running! Last night it pulled out really wet stuff, was liquid like pee. Really looked like pee. About an inch of it. there is .25" of 'pee' in the cup now, but I played around with the water height so we'll see what happens. I also got the stones to the bottom, all working now too. I am hoping for something gross in the morning ( in the collection cup, that is... lol ). I want to give a big thanks to Sasquatch for this. Really a big help. Whether its a plastic kidney, or a skimmer, I never could have done this alone. Pics to come soonish, I finished off the roll of filme.
