I was working on my pond today, and noticed tracks in the algea in the upper
pond. On closer examination I found quite a few small snails working their
way up and down the walls.

Is this going to be a problem and if so, what can I do about it??

This is the first time in the four years I have had the pond I have ever had
snails.

Thanks for your help.
