It appears to be a captive plastic of some type, perhaps had pores
to help - the tube rotates around and from the source tank to the
deposit tank. Think of a twisted dish towel (maybe) and it acting like
an Archimedes spiral that is in a loop and constantly pulling upwards.

Something like that. I noticed a large fender washer tie wrapped in the
loop to keep the plastic down in the mix. Plastic likely floats without it.

Oh, that's clever! Give that man a patent. Bob

I tried to view that damned thing and there is no joy. Not sure if it's my
dialup or the computer itself---but I'm grateful for the link. Thanks,
Mike.

Care to comment on what you saw? At this point I'm totally in the dark.
