I have, in my main tank some Marimo moss. I would like to take some and move it to 2 smaller tanks. The problem is that in my main tank I have little Malaysian trumpet snails. I do not want these snails in the smaller tanks and have seen them all over the moss before. Is there a way (I know there is, just can't remember what) I can treat the moss to be sure there are no snails and/or eggs?
