Re: [APD] Algae vs. Ultrasound?

I recall that this came up several months ago, so it should appear in 
the archives.  As I recall no one was exactly enthusiastic about it.  
It does seem to me that if the idea works it could be engineered to 
work in an aquarium, in such a way as to kill algae, but not plants and 
not fish.  (Just as CO2 helps plants, but  has to be limited so as not 
to kill fish.).  If I were 20 years younger I might want to work on 
this, but first I think I will try to learn just to grow healthy 
plants.  Tom????
