white spots in tank

I was wondering if anyone knows what these are. I'm worried they may be from over feeding or something I'm doing.

I have 0 ammonia, 0 nitrite and 0 nitrate 8.2 ph and calcium last tested 3 days ago was 300 mg/L and we put bionic part 1 and 2 since then, now calcium is 390 mg/L is that too quick an increase?

I do see the white specs now on the power heads too, mostly in the shaded areas of the rocks. Heres a pick to help identify.

Likely Serpulid worms, a small harmless critter in the feather-duster family. Newer tanks usually have outbreaks of them and they will flucuate depending on nutrient availability. Not to worry.

Tank is pretty new! Thanks for the help.

I agree. I have them in my phosban reactor and in some of the shadier places of my tank.
