Somewhere in the APD archive I found that KMnO4 should be used either at
1:1000 for 30 sec or 1:100,000 for 30 min to kill snails and other bugs
from plants to be introduced in the aquarium. I used it at 1:50,000 for
1 hour (thus roughly 4 X the recommended dose) and didn't rid completely
of snails. I guess snails die but their eggs are much more resilient.
Next time I'll increase the dose even more. Plants didn't seem to bother
anyway.
