I see a lot of theory, but no data.

My skimmer creates a thick cloud of very fine bubbles using very high pressure through a penductor (two of those). The bubbles are not individually visible. The water just turns solid white. As they mix with the reverse flowing dirty water, the bubbles coalesce and eventually (12 ft up) create a thick layer of dark foam and brown liquid.

Some bubbles are so small that they don't rise. They flow with the downward water flow instead and exit the skimmer. They don't pop. They also don't seem to float well. They look more like particulates. In the complete absence of water motion, they will eventually rise.

I'm open to all plausible theories. Just need data.
