What are these white spots?

[LadyL]

Hi,
yesterday I noticed that I have white spots growing on my live rock. Can anyone tell me what these are? They are very small on the majority of my rocks but there is a big one on one of my rocks. Hopefully the pics are clear enough. I had to use my phone camera. Thanks!

Unfortunately it is very difficult to tell from the pics. Any chance of getting clearer pics?

I'd just hate to venture a guess...and more than likely the larger white spot is something different, so pics of each would be most helpful!

Without seeing a clearer picture or knowing what you have in your tank, I would almost say they are Nerite Snail eggs. I have them in my tank as I have 4 Nerite's(who do an AWESOME job at cleaning!) If you have no Nerites, then I am at a loss.
