Found those on my quarantine tank glasses, maybe around 50 of these egg-sacs.
Only 3 Turbos, 5 small Nassarius snails and a couple of live rocks in the tank.
Thank !

Snails.

Well, marine gastropod is all I can say with certainty. Based on some light searching, I'm going to put my $1 down on Nassarius snails, though it's possible something else hitchhiked in somewhere with live rock or sand. Still, you'd have probably seen that something else by now if it were mature enough to lay eggs, so I'd predict a Nassarius population explosion sometime soon, especially since there's nothing else in the tank to make a snack of the eggs.

I agree that they are snail eggs, however I'm almost certain these are Nerite eggs. Nassarius lay their eggs in spongy, wavy lines while Nerite lay these individual, hardened eggs.
Definitely scrape them off the glass though, they can become stuck and leave little bumps.

I would absolutely trust this analysis more than mine.
