I just came across this product Physan 20 at the First Rays web site. I have been reading over what they offer while researching for both a vivarium I am planning, and also for some planned experiments growing some aquarium plants emersed. (Still have a lot of reading and thinking to do, so bear with me a moment here...

What I am curious about is if anyone has used anything like this to clean up any plants that have been hit with algae in one tank and where it would be nice to save it and get it ready for another tank without introducing the algae to the other tank.

In addition, it seems like a good idea to clean all aquascape type tools (scissors, tweezers) as well. I had not considered that before! I bet I have introduced algae that way already.
