Little baby snails everywhere

[Kay]

They have been around a while and I see them every day and especially at night crawling up the glass. They are also in my sand. Is that good or bad?

i would assume they are these - http://www.melevsreef.com/id/collonista.html

quite common, i have tons of them

They don't look like that, but it could be. They look like miniature turbos. But I hope they are chowing down on the algae.

Colinistas was my first thought, too. They don't get much bigger than a 1/4 inch and they can breed easily. The babys are about the size of a pinhead when you finally start to see them. They usually hide during the day and then cover rocks and glass at night. I used to have tons, and lost them when I had issues with my tank... I see a few and hoping they'll start to come back like before.
