Can sonic waves really destroy black algae?

Postby wbremner » Mon 14 May, 2007 10:31

I have started to see a couple of products coming on the market that purport to kill algae by using sonic waves. Apparently algae (but not humans) are suscetible to certain sonic frequencies (?) that break the cell walls down, killing the growth. It apparently works on all common algae types (green, yellow, black, etc), with lower requirements for chemicals, chlorination.

Sounds like the perfect soution for my black algae problems, but I'm sceptical. Has anyone purchased / used one of these products?

This technology has been available for fish ponds for about 5-6 years. I haven't used it in either, there is some science supporting this idea, however it is a little dubious that it will work as it should only work where the water passes through the sound waves, not the waves going all through the pool.
