White spots on glass. ID please?

[johnnyenv]

Hello,
I'm having huge populations across the entire glass of these small white dots. When I run the Flipper across them with the blade you can feel the resistance of them.

Any idea what this is. I have a picture of them on the glass.

Hard to tell without close-up, but they look like Spirorbid Worms

Spirorbid worms seems most likely.

They grow back within 2 days of cleaning the glass.
I can get a close up at the weekend when I get my macro lens back.

I'm trying to get Coraline to grow so I wondered if it was that.

Look at some images of Spirorbid worms and see if it looks like what you have.
If they are spirorbid, you have nothing to worry about. They're good guys.
