Any ideas what it is?

I appreciate any input.

Looks like green hair algae and cyano, possibly indicating high levels of nitrate and phosphate. I would remove/syphon as much as you can and adjust water parameters if needed. With this much algae your test kits may register artificially low levels because nutrients are bound up in it.
