Dang. That's what I thought. Just wanted a 2nd opinion.

Looks like dinos to me as well. Can't be 100% certain though. A few more slightly closer-up pics would help with getting a more accurate diagnosis. Microscope pics would be even better.

Not good as you know. When you siphon it into a bucket does it "reconstitute" into strings within a few minutes? If so, could well be dino. Really need a microscope to determine exact species and treatment - some dinos are photosynthetic and some are not for instance; some respond to uv light and some species don't seem to be affected by it.
Good luck, it is a challenge.

Ya dinos, can’t let nutrients bottom out, start dosing both
