eggs, but of what?

These little white puffballs are everywhere now, on the rocks, the christmas tree rock, the glass, even on snails..I am assuming they are eggs, but from what? We have astrea and turbo snails, red leg hermits, 2 emerald crabs, queen conch's, nasarius and cerith and cap snails. Now these things are pretty good sized.

Looks like your gonna have some snails. What kind? dunno..By the size, it may be the Mturbo snails. I understand they have been known to breed in captivity given the correct parameters and temp.
