I have used Potash alum, Potassium permanganate, bleach all . Potash alum and Potassium permanganate both are very good and effective to kill all the germs, snails etc.. but not the algae. As you know most of the plants we purchase contains some of the other algae.
With bleach you can get rid of algae, germs, snails.
From my experience snails has to be removed manually.Here what I do, after the lights off,switch it on after an hour or so in the Night, you will find that most of them or out on all over the place,take some energy drinks and start removing,repeat it when ever you are prepared.

I have never used Pot.Permanganate for sterilising plants so I'll reserve my comment.
Madan, Pot permagnate, irritates snails and other inverts, hence they leave the surface of the plants.
If you want to hunt for earthworms in garden soil, add a mild solution of pot. permanagte to the soil and after a few min, lots of earthworms and even snails will surface out. :wink:
Snail eggs, I agree are not killed by pot. permagnate.
