The G-Sonic 50 S algae killer is absolutely maintenance-free and effectively prevents algae growth, thus ensuring clear water. Already existing floating algae die within a few days, green algae within 3 to 4 weeks, thread algae after approx. 7 weeks.

The G-Sonic 50 S algae remover also causes the biofilm (algae mucus layer) on the walls to be broken down by up to 2/3 and thus effectively prevents pathogens (pathogens) from multiplying.

When swimming, at most an interval-like clicking sound can be heard, as the human ear can hear through the skin.

With a short-time timer you can simply turn it off while swimming. Due to the very low energy consumption of max. 40 watts, operation with battery-buffered solar collectors is possible.

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 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 ultrasonic algae control 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

Algae-free package: G-Sonic + pond mud sucker + filtered water repatriation

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 ultrasonic algae control 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 >.

High-precision clicks as natural algae treatment

Algae free by effective ultrasonic clicks
Algae free water by high-precision ultrasonic click tones, 100% natural and environment friendly

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.
