Help ID these purple specks

These purple/bluish dots are appearing everywhere. I will scrape them off and they come back in 2 days.

They look like tiny spirals if I look very closely.

Are they blue/purple when the lights are more white?
If under normal lighting they’re white, then the description sounds like spirorbid worms. They’re harmless filter feeders and common in just about every tank.

Yes. More white. Thanks!
