It is most likely that there was some disease or parasite in the new snails
that killed them all. I suspect that if you just waited a few weeks and
added new snails they would be fine.

Snails are full of parasites naturally.

I have lost pretty well all my snails Astrea Snails, Margarita Snails,
Cerith Snails. This happened after getting a few new snails which I
bought to try and control a outbreak of cyanobacteria/red slime. Did
the outbreak kill the snails? Should I get turbos instead? Could it
have been a snail virus?

Any help would be great.
