My planted tank is over run with snails. One of the biggest problems was a piece of driftwood covered in Java moss, probably had 100 snails in the moss. I removed the driftwood and replaced it with an extra piece I had laying around so now I can go after snails with a siphon during wc and they can't hide in the moss. Anyway, my question is for the removed piece. How long should I wait before using the driftwood from the infested tank to ensure any eggs are dead?
