We get quite a few questions about various aspects of ultrasonic algae control, as well as other ways to keep algae down in your pond. Listed below you'll find our responses to those questions and hopefully they'll be useful for you and your pond.

Q. Will ultrasonic algae control work in my pond?

A. Most likely it will.  The main thing to remember is that there are many different species of algae that's present in the environment.  Most of these are positively affected by sonic control.  However a few species are quite hardy and may not be as easily affected.  Many ponds as well often have several species of algae growing in them at one time.  What we recommend is that a water and algae sample be taken from the pond and sent in to us for analysis.  We review the results and compare it against a historical database of effective treatements.  We then make a recommendation on if the system is right for your pond. 

As a side note, even if you find that ultrasonic algae control isn't the best route to go, there are other non-chemical options that you can use that might just get the job done.  You can read about them on our algae control products page.

Q. Is Ultrasonic Algae Control safe for my fish?

A. Yes, ultrasound has proven to be very safe for fish and other aquatic wildlife.  It's important to note that our ultrasonic units are fequency tuned to damage the cellular wall of the algae.  The frequency range is not harmful to other wildlife. 

We have personally tested the devices in Koi ponds and other fish ponds and not only noted no ill affects, but the fish would swim up to the unit, look it over and then slowly swim away.  There was no indication of any kind of stress or reaction caused by the application...other than a bit of curiosity by the fish themselves!

Q. Does Ultrasonic Algae Control work on all types of algae?

A. Ultrasound can work on most of the more common types of algae found in ponds today.  More specifically, ultrasound works very well and quite quickly on planktonic algae, or green water issues.  Since the density of this algae growth is very light, the sound waves can penetrate and move through the algae quite easily.  Usually in a matter of a few days, the green water can be eliminated.

Algae that has a higher density or heavier mass to it such as string algae can take longer to eliminate.  In reality the sound waves must work their way through the mass, killing the cells along the outer wall of the bloom, a bit at a time.  Once the bloom is gone, or treated in some way to eliminate it, then ultrasound can work very well at keeping new blooms from forming.
