Lots of baby snails...now what do I do ??

[BCOrchidGuy]

I had something new show up on my glass this morning, tiny tiny clear things that have what looks like minute grains of sand in them. I don't notice them moving but they sure look different than the tiny tube worms I mentioned earlier.
Since all my fish are out of the tank I wonder if maybe they are snails, with nothing to eat them maybe they are growing..... have to keep my eyes open and see what develops, I know I did have lots of cerith eggs all over the place behind my LR....
