This is a new one for us in 20 years of ponding. This stuff lays on
top of the water, which is clear under it. I tried skimming it off
but it is so fine much of it just goes thru the skimmer. We have a
sidewall skimmer, and 3 barrel filtration system. Brushes in the
first, springflo in the 2nd, and quilting batting in the 3rd. DH just
cleaned them and said he'd never seen so much muck/mulm. The rows of
brushes were so heavy with gunk that it too 2 hands to lift them out!!
Back to the green stuff, it sticks to everything, even hands, mine
were neon when I took them out. It gets on the fishies noses when
they eat. UV light was just reinstalled Friday, and water under slime
is clear. What is this crud, and how do I get rid of it? I've
thought of seining it off with some fabric, but thought I'd check here
first. Also, DH put our yearly salt dose in a week or 2 ago.

Thanks for any ideas or help. BTW this is not an oil slick, no
rainbows or anything other than GREEN!!!

The colour makes me think of Spirogyra. Could it be in early stages and not
filamentous yet?
