How it works
Ultrasonic algae treatment devices have a speaker that sits under the surface of the water. The speaker emits high frequency sound waves into the water. The sound waves are tuned to vibrate and burst algae cell walls, preventing the algae from reproducing. The sound waves are safe for fish, animals, plants, people, and beneficial bacteria in the aquatic system. Still, most manufacturers recommend proper pond maintenance, filtration, and aeration to promote the growth of beneficial bacteria.
