i have these weird white things on my glass.. i know they aren't just a deposit of some sort because i can crush them with my nail.

it seems like they are like a half of a clam mixed with a snail..

they are very tiny and all over my glass.. anyone know what they are and if/how i can get rid of them?

They're limpets. Annoying if they are in vast numbers so control your feeding.
