The LG SONIC XL was the first of the long range ultrasonic output devices developed by LG SOUND and will handle ponds up to a maximum of 3.8 acres with a reach of 100 meters. The key to effectiveness of this device, as well as all of the LG SONIC line of algae control products, is the transducer or the underwater ultrasound emitter.

The transducer was designed and created for LG SOUND for the express purpose of creating a resonating sound wave at the optimum frequency that breaks down the fragile algae vacuole cell wall, thus causing the algae to die. LG SOUND has the exclusive rights for this type of transducer, so it will not be found on any other device of this type.

Though the LG SONIC XL unit has now been surpassed in range by the XXL unit, it has remained a popular solution for smaller ponds based on its well earned reputation and moderate price.

In fact, each of the different models have been designed for a specific effectiveness range and have been updated to the latest technology advances in circuitry and transducer design.

The market for this super algae killing device

Testimonials from users in many countries with relevant pictures of their experiences with the LG SONIC XXL are available for seriously interested professionals.

Installation is quite simple:

The electronic box has to be mounted in a dry, covered place. Like all outdoor power supplies, a ground fault circuit breaker or receptacle is highly recommended and may be required by your local electrical code. In the US, the preferred power source is 120 volts AC, the typical household power supply. Solar panel electrical units can be provided for remote locations or for those where the cost of providing a power outlet is high or difficult to reach.

Avoid coiling any excess wire to the transducer as this can set up an induction field and reduce the signal output power. Either criss-cross the excess cord (Z pattern) and secure it with electrical tie straps or the cord can be shortened from the end that plugs into the circuit box. Please inquire for shortening instructions if needed.

After putting the plug from the transducer cable into the corresponding socket of the electronic box, place the transducer (and float combination) in a suitable location in the water so that the front “looks” through the water mass and covers as much as possible of the water that has to be treated.

The unit begins operation the moment it is plugged in to the power source. A blinking light will indicate that the ultrasonic signal is being sent to the transducer (in the water). At no time is electrical current being placed in the water. The power is used to vibrate the face of the transducer to create the ultrasonic wave, like an underwater speaker.

The ultrasonic vibration waves leave the transducer (opposite end of the power signal input cord) in a 176º arc (semi-circle pattern) expanding vertically and horizontally outward. Within a day or two you may begin to observe the first results under a microscope. As the algae are destroyed, many of them will float to the surface. When you see this you can be assured the unit is operating properly. You can leave the dead algae to decay naturally or remove it to speed up the overall process. If a lot of the algae floats up, it can reduce the signal reflections that bounce from the water surface and reduce the signal power beyond it.
