Staghorn Algae--How to deal with it without killing plants?

So, a while back I had some plants that were really close together, that on top of poor circulation caused some staghorn algae to grow on them. I killed majority of my plants and worked at tending to the bits that seemed to have escaped this mess...

A year later, I haven't had much problems with it, till I noticed some on a snail's shell! First of all, this gives me a awful, but kinda cool problem. While the Algae looks neat on the shell, it's started to spread to my Sunken wood. In order to kill the algae, I simply need to remove the log, but then my entire stock of Java Moss dies with it... The snails are snails that suffered from a calcium deficiency, which I have made progress on the younger snails to keep them from this fate, and that's the areas that the Algae have clung to.

Any suggestions?
