Hi..... make sure your tank is not getting too hot durring the day. Just a
thought... that happen to me once... Also check the nitrates reguardless of
what kind of top off water you are using.

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.
