Help identify these white spots

[nightmarepl]

hey guys found some white spots all over my rocks snail shells empty shells pretty much everywhere

My first idea was to poke it and rip them open looks like a dust comes out i suspect snail eggs or something looks like eggs that’s for sure isn’t calcium cause it’s only on the rocks and shells not on my tank or plumbing and calcium scraps tougher this is soft

Could be white algae. It doesn’t usually grow on glass
