Never heard of this method before.
I wonder what the fish think of 40K-100KHz strong vibrations throughout the 
water!

But the question I have to ask is, why don't they make a model for domestic 
Aquarium use if it is so effective? Huge market surely?

I suspect it doesn't work in the close confines of a glass tank or that it 
kill the plants? They claim it kills Algae and Fungus. But not fish or plants.

I see they have a Test PDF

If it kills Chlorophyll surely it's going to affect plants?

But it would be nice to think that it could work. :-)

I'll just look up Radio Spares and see how much a Ultrasonic transducer 
costs to build... ;-)
