Millions of little white hairs in my aquarium.

[starfishguy869]

Hello, today, I just woke up and found millions of tiny hair strands in my aquarium. My ammonia is reading 0 so I don’t think it’s overfeeding. I have also not added anything to the water and just constructed a diy lid for my aquarium. These definitely

aren’t worms. My biggest concern is that they will suffocate the corals and fish might eat them. . If anyone could tell me what is happening, that would be great.
If it helps, they range from 2 mm to 5 mm

its hard to tell with the focus and lighting. try white lighting and maybe more focus.

I know I have had "hairs" like this but it was just an algae bloom
