Cyano or hair algae?⁠
I tried to upload a video but was unable to. It shows the hair-like strands flopping in the current. I do not have any slime-like patches. It is growing on the sand and rocks but not the glass. Nitrates are zero with Nyos test and Phos fluctuates from 2-22 ppb on hanna checker.

Both of those, Cyno & GHA, thrive in low nutrients. It’s been my experience that GHA is harder to get rid of.

It looks like cyno to me. Check this link and you tell us

Does anybody find any special CUC beneficial in the battle against Cyano?

I would use chemiclean if water changes aren’t working.
