Functionality of the click tones against algae

The G-Sonic algae control device generates acoustic click tones and sends these signals to the click generator. The click generator is the loudspeaker under water, which emits the click tones as a complex sound wave pattern under water.

The clicks act on the vacuole of the algae, a microscopically small bubble, a cavity in the middle of the algae cell that refracts the light. The vacuole resonates until the membrane filled with cell sap cracks.

Green algae – Chlorophyta, Chlamydomonas, Spirogyra, Cladophora, Hydrodictyon, Volvox

Effect of high-precision click tones on green algae: The click tones damage the vacuole, till they tear and the algae dies naturally.
  • Existing green algae usually die within 2-3 weeks, depending on the type of algae; in the case of thread algae, this process can take up to 6-8 weeks.

Blue-green algae – Cyanobacteria

Effect of high-precision click tones on blue-green algae, bacteria. The click tones damage the gas vacuole, till they tear and the algae dies naturally.
  • Existing blue-green algae usually die within 1-3 weeks, depending on the type of algae.

With the click tones, all native algae species, such as green algae, thread algae, slime algae, brown algae, brush algae, beard algae and blue-green algae die due to natural stress.

Due to the methane gas present in the thread algae, the dead algae rise to the water surface where they can be sheared off. The dead thread algae can now be easily removed and the result is quickly visible. In a rain shower, the methane gas reacts and the dead algae sink to the bottom of the pond. All other algae species decompose into tiny particles of 1-2 microns and sink to the bottom.

The permanent use also prevents the formation of new algae.

Studies and experiments have shown that neither flora nor fauna are affected by the algae eliminator. The click tones are completely harmless to humans and animals, including fish. The desired aquatic plants thrive much better and the water becomes clearer.

Click tones and biofilm

The biofilm, algae film, mucus layer, coating, growth, mouldy skin or sewage skin is a thin mucus layer that is often found at the edges and at the bottom of ponds. Many microorganisms (e.g. bacteria, algae, fungi, protozoa) are stored in the biofilm. Due to the nutrients present in the biofilm or mucous layer, algae can multiply very strongly. With the help of click sounds, this biofilm is reduced by 50-75%, so that pathogens have a much lower chance of survival. At the same time, the “slimy” layer is reduced by 50-75%, which makes the device ideal for swimming ponds.

Click tones and environment

The algae eliminators are environmentally friendly and free of chemicals. The sounds emitted by the device are not audible to humans and do not harm animals, fish or plants. This was confirmed by different universities (among other things university Gent) after long and detailed experiments at ponds (applies also to swimming ponds) and aquariums. Click sounds are produced in nature by many animal species, such as bats, dolphins and whales. Under water, humans hear the click sounds depending on their hearing ability.

Click sound propagation

Click sound propagation
Click generator sound propagation

The click tones are emitted by the click generator over a radius of 180°. The range depends on the model of G-Sonic algae free device. Placed at a favourable location at the edge of the water, the units can radiate sound to a semicircle with a radius of up to 150 metres, depending on the type, thus treating a water surface of up to 300 metres around the unit.

Position of the click generator

The click generator is placed in a favourable position at the edge of the water body in order to sound as large an area of water as possible. If you have a second external pond, it must also be equipped with an algae eliminator. The circuit must be closed, otherwise fresh algae will be added externally and the water object will be constantly “infected” with new algae.

Click tones and safety

Security is a major concern. All algae free devices have galvanic separations with additional fine fuses. Only one loudspeaker signal is sent to the click generator, with the G-Sonic swimming pond (S) models max. 24 Volt. All algae free devices are CE compliant.

Algae Control in Pond, Biotope

Every garden friend who can enjoy a biotope, pond or his own green oasis will have experienced sudden algae growth. Such increased algae growth is usually due to an excessively high nutrient content in the water. Expensive algae agents and chemicals, so-called algae destroyers, are often used. The problem can be tackled gently and environmentally friendly with click tones.

For the different sizes and forms of ponds, there are corresponding devices and Positioning Variants. You can choose between the G-Sonic 5 , G-Sonic 10 / S, G-Sonic 20 S, G-Sonic 50 S with ranges from 5m up to 50m and the G-Sonic 100 for large ponds and biotopes.

The effect of the click tones sets quickly. Suspended algae already die after five days, Depending on the species, filamentous algae will come to an end after four weeks.

The generated click tones are harmless and without side effects for humans, animals (fish, amphibians) and plant. Fish & amphibians have hearing ability from 50 Hertz to 800 Hertz and do not perceive the click tones.

Except for the ornamental ponds the click generators can be used also in lakes, ponds, swimming and fishing ponds and biotopes. Fish suffer a great deal from algae, which are oxygen content of the water decreases and the PH value of the water in the pond gets worse. Noxious gas bubbles that are present there can cause inflammation, settle in the gills of the fish solid.

Tip from Algae-free

You do not need to install a Professional, with the help of the instruction manual, it’s child’s play. Once in use, the device does not require any maintenance and the Algae control runs automatically in the background!

Natural Algae Control & Removal

Keep garden, koi, natural, swimming ponds free of algae by effective click sounds & without chemicals.

Algae polluted biotopes and ponds are unpleasant and annoying for owners and users. In many cases, pond and garden owners resort to chemicals to curb algae growth. However, if gardeners want to be more environmentally friendly, then there are alternatives.

Kill algae naturally and remove algae easily, effectively & environmentally friendly by the G-Sonic Algaefree controller.

Natural & ecological algae control 

The Algae killer takes place with high-precision clicking tones, without chemicals or power consuming technologies, e.g. UVC lamps, ozon.

Acoustic signals are sent underwater, causing the hollow bodies of the algae cell to enter and tear into a resonant vibration. The algae dies completely naturally and ecologically within a few weeks. The algae release device fights the algae in the garden pond and provides long-lasting protection against new algae growth.

The algae-free package, carefree and easy use for pond & pools care with clear water results

The pond should definitely be cleaned several times a year to remove the bundled nutrients, i.e. impurities such as dead algae, leaves and mud, from the water. This is possible, for example, by a professional pond sludge sucker.

The pond cleaning also includes filtered water repatriation with a fine filter. Thus, the pond is cleaned and purified in every way.  Detailed information about the algae-free package can be found here:

The intelligent click technology is very simple

The G-Sonic device emits high-precision acoustic click signals in several frequencies which are not audible to humans or pond dwellers. The frequencies of the click-tones are precisely tuned to the diameter of the algae vacuoles bringing them into a self-resonance vibration. As a result, the vacuoles tear apart, leading to the death of the algae due to stress. Existing algae die within 2-3 weeks, floating algae within 1 week, making the water clearer. It can take 6 to 8 weeks for tough thread algae till the cell wall to rips. More about the functioning >.

ClickSonic’s ultrasound click technology reduces algae by up to 90% and prevents the growth of new algae, so well existing algae. Being very environmentally friendly for a healthy ecosystem and long term solution. Ultrasound (high frequency inaudible waves of 20KHz) are also produced in nature for example with the fall of water, whether rain or a waterfall on to a hard surface. These accoustical ultrasonic waves can then be used without prejudice for the eradication of algae. Under normal conditions the algae formation is reduced up to 90%, saving maintenance costs considerably.

Clear water without chemicals and algae agents

The effectiveness of the ecological process has been confirmed in many studies, the independent Swiss biologist and water specialist Dr. Peter Bossard emphasizes: “Click tones can be used to combat algae growth in ponds with little effort and limit it. Without having to use environmentally hazardous or even toxic algae products or chemicals. ” In addition, the method can be used almost anywhere. It is only necessary to find the optimal position of the click generator in the water. The device emits acoustic waves in the area via human hearing, which gradually reduces algae growth. “The algae usually die within two to three weeks, but the water becomes much clearer after just a few days,” says Martin Studer, managing director of manufacturer ClickSonic. The company manufactures devices with ranges of five to 150 meters and also advises where to place in the water. Floating algae, flowering algae, green algae, green algae, filamentous algae and bluegreen algae, cyanobacteria can become a major problem. Environmentally conscious and without large technology and expensive algae remedies, the algae problem can of course be tackled without the addition of chemical agents.
