White coralline algae?

[keithw]

I have little white spots growing on the glass of my tank. It's only on the back section which is painted black. I thought it might be coralline but that stuff is usually colorful.

I have them as well, seem to be growing in equipment as well, not on the rock.

 

It seems to feed on calcium / kalkwasser

Ya that stuff is just little tube worms. I have thousands.... The only white coralline is dead coralline btw.

They're small tube worms called spiriboid(hope i spelled it right!) they have little red "feathers" and look like mini coco worms.

Oh damn, thats really cool. I looked at them with a magnifying glass and you can definitely see the little red part
