I have these white/grey "things" starting to pop up all over my tank. there are about 4 of them. Along with other white/grey circles that are about a cm in diameter. Any ideas?

Q-tip sponges, they'll cause no trouble.

As Samurai_Sushi said - "they'll cause no trouble". I think it's a good sign your tank is coming along nicely...

They usually pop up in new tanks and go away after a while.
