white spirals
 

I have these white spirals all over the glass and the wavemaker in my tank. I have no clue what they are...
They are white spirals and are really stuck to the glass. If I scratch them off they come back. There's quite a number of them.
any ideas ?

are the in a line, maybe there are snail eggs. do they look like this?

Or do they look like small shells, about 2 -3 mm across with feathery fronds poking out like fans? If so they are filter feeders.

Or they are just snail eggs of a different kind. Leave a patch of them alone for a while and they'll grow into something a bit more familiar.

I think I know what you are talking about. I would not worry about them. They are filter feeders. You will grow lots if you have a high nutrient system.

will they hatch?
 

I have the exact same thing on my glass. They appeared about two days ago. My tank is only about a month old now and has just completed its first cycle. As I am new at salt water tanks, I am wondering if anyone knows if they will infact hatch and provide me with additional snails in the future? Any feedback would be great:razz:
