Water Reservoir, Water Tank

Greenhouses, Tree Nurseries, Plant Breeders & Co.

Algae cause major economic damage in water tanks, water reservoirs for greenhouses, tree nurseries and plant breeders. The algae have a negative effect on the water quality, reduce the light irradiation as they colonize glass surfaces, pollute or clog filters.

Water reservoir for plant cultivation, tree nursery

The fight against algae requires a large use of working time and cleaning agents, chemicals of various kinds, which will reduce the productivity of the company and massively increase costs.

The G-Sonic-50 is suitable for algae control in large tanks and pools. The effect sets in quickly. Suspended algae die after two to three days, green algae after about three to four weeks. Once in use, the device does not require any maintenance.

Example tree nursery

With the use of two G-Sonic 10, the water reservoir is free of algae. No new algae are produced and the filters no longer clog. The cleaning effort has been reduced enormously.

The investment pays off very quickly

  • In the water basin (diameter 20m) were always many algae, which clogged the filters. A cleaning of the water basin had to be carried out several times, which led continuously to a considerable expenditure.
  • The nursery can irrigate the water for deciduous trees, conifers, fruit, berries, roses, hedge plants, avenue trees, ornamental grasses, climbing plants, bog plants, bamboo, ground cover plants, shrubs and Mediterranean plants without clogged filters by algae and the working time is considerably reduced.
  • The glass surfaces become more translucent, air, water and soil quality improve and consequently plant growth increases.
  • Cleaning agents and chemicals are saved or can even be dispensed with.
  • Glass and floors need to be cleaned much less frequently.
  • Nutrient-rich water can be reused, water recycling.

Many plant diseases are caused by germs and bacteria in the water. Dutch and Belgian plant breeders, for example, use chemistry to combat the cucumber green mottle mosaic virus (Cucumber green mottle mosaic virus). In many cases UV disinfection is used, in which the plants are irradiated with ultraviolet lamps (UV). However, the combination of UV and click tones is far more successful than if only UV is used. An example of this is the significantly higher performance of the lower power consumption when UV is supplemented with click tones. The reason for this is the increased monitoring of the water treatment with the effective click tones.

Sonic Antifouling for Powerboat, Sailboat

Motorboat, Ship, Yachts, Catamaran, Trimaran

Ship hulls littered with algae and shells are a great nuisance for every boat owner. Not only is the unattractive appearance annoying, but the ships also suffer long-term damage from the algae. In the beginning the algae and mussels make the materials rough and destroy the paint, after a longer time the hulls even become brittle. The protective coatings often used, on the other hand, are an expensive, labour-intensive and environmentally damaging measure.

Sailing without algae, mussel growth for more speed and fun

The Y-Sonic Antifouling Algae Cleaner reliably prevents the adhesion of algae by means of click tones. Already infested hulls will also be freed sustainably. The effect sets in quickly, after a few weeks the algae die off and can be wiped off.

Suitable for boats, yachts, catamarans made of GRP, steel or aluminium. For catamarans the application per hull should be used. Depending on algae infestation, up to 10% fuel can be saved during engine operation. By installing the antifouling system, the hull speed increases through the water, reducing the resistance in the water.

Hull from motorboat algae-free

Are antifouling paints still necessary?

We always recommend the combination of antifouling with our click system. Nevertheless, we have very good references without antifouling, only with our click system. The ship’s hulls are freed from algae and kept free exclusively by high-precision clicks. The nutrient concentration in the water is decisive. For example, if there is a high level of algae in the water or the gelcoat is of poor quality, antifouling may have to be applied in addition to the click system. The combination of antifouling with the algae eliminator always works better than each individual system.

The installation of the algae collector is simple: the click generator is attached to the inside of the ship’s hull (ideally in the bilge). The click tones are then through the entire fuselage. You do not need a specialist for installation. Once in use, the device does not require any maintenance.

The purchase price of a Y-Sonic 10 / Y-Sonic 20 is refinanced within a very short time and the effective system eliminates the need for expensive antifouling paints.

Thanks to the algae-free hull, the boat glides through the water with little resistance. With the algae remover an antifouling coat is not necessary every year.

Y-Sonic installation

The installation can easily be done by yourself or by your local shipyard. Our Y-Sonic Antifouling installation manual is supplied with the device.

More Information

Green Algae, Thread Algae in Waters

Algae cover the ground, green algae float on the top.

What are algae?

Algae are low plant organisms, mostly living in water, which are organized as unicellular organisms or as multicellular organisms. The name “Alge” is a colloquial, non-organic name.

More than 3 billion years ago life began with the first green creatures, the archaebacteria and cyanobacteria. These are also called blue-green algae.

What do algae need to live?

Algae don’t need much to live on. Nutrients from the water such as phosphate and nitrate, but above all sufficient sunlight are sufficient for them.

How do algae originate?

Algae produce biomolecules from water and carbon dioxide. The green substance chlorophfeyll, which converts sunlight into energy (photosynthesis), is present in the cells of the algae. With the help of light, carbon dioxide (CO2) and nutrient salts (phosphate, nitrate, etc.) the cell substance of the alga grows and produces fats, proteins and sugar.

The alga is divided into different groups:

  • Prokaryotes – organisms without a cell nucleus. Prokaryotic algae are called cyanobacteria, blue-green algae or smear algae.
  • Eukaryotes or eukaryotes – Organisms with cell nucleus and cell membrane, approx. 10-100 times larger than prokaryotes.
  • Eukaryotic algae are all other algae: Green algae, brown algae, diatoms, euglenophyceae, dinoflagellates, chrysophyceae, haptophyceae, cryptophyceae, etc.

Green algae and thread algae

To the Grünalgen belong also the thread algae which in the pond with Nährstoffüberangebot and seichtem water gladly spread out, to the plague become.
Green algae and thread algae in garden ponds

Green algae also include thread algae, which form green algae mudflats and are very common in ponds. In the classical classification of algae, the chloromonadophyta, yellow-green algae, gold algae, diatoms and brown algae are counted as classes in the heterocontophyta group.

Filamentous algae are sometimes referred to as thread algae or pond foam. They appear like fine green threads that form floating carpets and are often moved across the pond by the wind. These algae are often found on rocks, flooded trees, other aquatic plants and jetties.

Macrophytic algae resemble real plants because they seem to have a stem and leaves and are rooted in the soil. A frequently occurring macrophytic alga is called chara or musk grass (because of its strong musk-like odour). Chara feels rough when touched due to lime deposits on its surface. This has brought her another often used name – stone root.

Algae problems

For the most part, algae are of little value for your garden pond or lake. The filamentous forms (thread algae) and the plankton have a gigantic reproduction rate and their sudden death can cause an oxygen deficiency. The oxygen needed for the fish in ponds and lakes can be provided by other aquatic plants in the pool that would thrive without competition from the algae.

Algae problems are usually caused by an excess of nutrients (nitrates and phosphates) in the pond. From the moment a pond is created, nutrients from the environment are washed into it. The older a pond gets, the more nutrients it has accumulated and the more susceptible it is to algae problems. The water derived from fertile fields, meadows and pastures, forage grounds, disinfection tanks and irrigation fields accelerates the accumulation and growth of algae in the pond.

Excessive algal growth will atrophy or suppress other forms of aquatic plants. In addition, the sunlight required for normal growth is blocked. Problems with the taste and smell of drinking water and sometimes even the death of fish are also associated with the excessive growth of plankton. Filamentous and macrophytic algae often form dense plants that make fishing, swimming and other recreational activities almost impossible. A complete coverage can prevent the penetration of sunlight and restrict the production of oxygen and the food components needed for good growth of fish stocks. If the presence of algae prevents the planned use of the pond, a method of controlling the algae should be considered.

Algae control

The algae explosion and carpets from thread algae can be removed with a rake, a cheese-maker or similar equipment. However, this method of algae control is very labour-intensive and offers only temporary control. In some cases, the algae seem to regrow just as quickly as they are removed.

Before using chemicals you should consider the possible contamination of household water supplies and waiting times for irrigation of livestock, fish consumption, swimming and possible skin irritations.

A “biological control” occurs when one life form is used to control another or to manipulate the biological balance in such a way that an unwanted plague is adversely affected. It is wise to be cautious when deciding on biological control. It can subsequently turn out to be unfavourable if the life form introduced becomes a greater problem than the original plague.

“Barley Straw” was tested in England by the Centre for Aquatic Plant Management for the possibility of controlling plankton and filament algae. These tests have been continued continuously over the last 15 years. “Barley Straw” and other straw species have been used in the United States occasionally with very mixed results and will not solve the problem. can be completely resolved.

Further algae information and tips

Fighting thread algae

The “thread algae” is not a botanical-systematic term, but a collective term for algae visible to the naked eye – tufts, balls, cotton tufts or mats. Thread algae grow and stick under water to aquatic plants, stones and dead wood.

Thread algae tufts, wads or mats as they appear typically in garden ponds

Thread algae in spring and summer

Thread algae develop very quickly in spring and early summer because they are the first nutrient consumers in water. By the time the aquatic plants grow, thread algae begin to grow at lower water temperatures. Due to this advantage, the thread algae grow almost explosively.

Thread algae are green algae

Thread algae have different manifestations. Mostly they appear as long thin threads (from a few centimeters up to several meters), which are partly interwoven in themselves. In many cases, the long-threaded green algae are interwoven in such a way that they can hardly be untangled.

Depending on the time of day, thread algae rise up and float as mats on the water surface. If they sink, they cover the bottom of the pond. Thread algae are adaptable and can become accustomed to chemical poisons, so that they become more and more resistant to them with the increasing use of chemical agents to combat them.

Thread algae develop when the water values are too high, i.e. the nutrient content in the water is too high. Usually a too high phosphate (phosphorus) value is the cause for the thread algae formation. With a lot of underwater plants you can contain thread algae after several years.

What to do against thread algae?

With high-precision click tones against thread algae: The click generator sends click sounds under water through the pond that are above the hearing frequency of humans and animals and are not audible. The vacuum in the middle of the algae cell, however, is resonated until it breaks and the algae dies.

Existing thread algae within seven weeks. By manually removing the algae during the transition phase, the phosphate in the water, one of the main nutrients of the algae, is removed.

How does the phosphate get into the garden pond?

Phosphate and other nutrients are contained in lawn fertilizer and nutrient-rich garden soil and are often washed into the pond by heavy rainfall. Also fish excrement and remainders of fish food as well as foliage promote algae growth.

Tips for combating thread algae

Thread algae have long Fäden
Thread algae have long strings & enough nutrients to grow up to several meters length !
  • When constructing the pond: ensure good shading and install very shallow areas.
  • When colonising the pond: use fast-growing aquatic plants, combination of pure underwater plants and marsh bed plants, use none or only very few fish, use thread algae repellents (such as Koi, Siamese trunk barbs) only in fish ponds.
  • When maintaining the pond: Do not fertilize pond water, minimize water exchange (no flow), cover the pond in autumn with a leaf fall net, place tannin-producing peat bags or sacks of rye straw in the water, fish thread algae by hand.
  • EM Effective microorganisms: Starter bacteria support pond cleaning, counteract turbidity, strong odours and algae growth. With controlled plant growth, zooplankton, which serves as food for numerous other aquatic organisms, can develop and thus create the basis for a stable and closed cycle. This is important for the development and preservation of the water. For optimal results, EM is combined with an algae eliminator.

Pool Robot Test & Comparison

In summer, taking a refreshing swim in your own pool or swimming pond is a highlight in hot temperatures. Natural pools must be cleaned manually or automatically. The Pool Pond Robot Comparison and Test shows what you should pay attention to.

Further informationHow can the pool robot clean the wall?

Professional pool robots not only clean the floor, but also the walls. The pool robot moves along caterpillar tracks like a tank. Wall cleaning is done by a vacuum on the underside of the pool cleaner. the pool robot is generated by its built-in motor.

Is individual programming possible?

Various programs that can be called up are built into the pool cleaner. A function only floor or floor and wall cleaning as well as the running time are mostly freely selectable.

How long does automatic pool cleaning take?

Normal cleaning usually takes 2-3 hours and the pool robot randomly moves through the pool until it has cleaned everything. At the end of the cleaning cycle, the pool cleaner switches off automatically and can then be removed from the water to clean the filters.


The algae eliminator can be installed quickly and easily within five minutes. The click generator is connected to the control unit by means of a connecting cable and inserted into the water object. It should be placed in a favourable position at the edge of the body of water so that as large an area as possible is covered with sound.

Click generator positioning

The direction of radiation of the click generator should always be in the longitudinal direction of the body of water. The range depends on the performance of the algae eliminator.

Left: optimal position of the click generator / Right: left
  • Left: The optimal position of the click generator
  • Right: no click tone propagation left and right behind the click generator

The algae freeing devices can be easily positioned and fastened if necessary. It was supposed to Make sure that the click generator is aligned horizontally and is not covered by mud, stones or plants. The click generator (KE) should ideally be positioned 10-15 cm horizontally below the water surface, as photosynthesis and algae production take place in this water depth.

A pipe clamp with plastic inner hole for fixing the click generator is supplied with each algae eliminator.

Peripheral zones, shallow waters

In shallow waters (depth less than 50 cm) or in the shallow water zone of a swimming pond, the outgoing signal is slowed down and the algae eliminator loses about half of its effect. This must be taken into account when selecting the right device.

In a pond with edge zones of 5 m, for example, it is therefore recommended to use a G-Sonic 10 (range 10 m) and no G-Sonic 5 (range 5 m).

The following should be avoided

  • Continuous feeding of refill water, e.g. spring water, tap water or fresh water of more than 5% per day can lead to algae growth,” as nutrients are infiltrated by the refill, which promotes algae growth.
  • Water impacts (waterfall, fountain) the propagation of sound waves. Therefore, the click generator must be inserted deeper so that the click tones can spread below the impact depth. An alternative may be to let the waterfall or fountain run only sporadically, maximum 3 hours a day. This interrupts the proliferation (cell division) of the algae only briefly.
  • Sound barriers: Larger stones, plant pots and other obstacles must be removed for optimum sound propagation.
  • Flowing water should be avoided, as the effective click tones are hindered by the water flow.

Tips for pond cleaning

To make the pond water clear, the water object should be cleaned with a pond sludge vacuum cleaner with water recirculation. Most errors occur during cleaning, when too many nutrients get into the water during refilling. When more than 5% of the volume of refill water (ground water, spring water, partly also tap water) is fed (e.g. during cleaning), nutrients are added to the water object, so that the water biohousing process starts all over again.

Low-nutrient rainwater is much less problematic. The so-called First-Flush (rainwater of the first 10 minutes), on the other hand, should not be collected as it contains large amounts of pollen, pollen and pollutant particles. Tap water or tap water is generally low in nutrients. Nevertheless, there are large differences that depend on the water supply. The water values can be requested from the water supplier or simply determined with the help of a water test. For phosphate-containing water we recommend the PO4 Phospatbinder for a short time.

Conclusion: When cleaning a pond, care must be taken to return the filtered (nutrient-poor) water and not to top it up with nutrient-retaining refill water from the tap, ground water or well.

Several ponds

If several ponds are connected together, each one must be equipped with a click device. The cycle must be closed, otherwise fresh algae will constantly be added externally and the other water objects will be “infected”. This would lead to algae growth before they could be killed by the algae eliminator. As an alternative, we recommend separating the water objects and providing each with an algae remover.

Both the electronic box and the click generator can be mounted inconspicuously without any problems and are therefore not visually noticeable.

The electronic control unit can easily be installed outdoors and is temporarily waterproof (IP67, dustproof, protection against strong water jets, protection against temporary submersion). We recommend to mount the electronics box from 50cm floor or to put it in a dry shaft, fix it.

When the device is switched on (mains plug connected to the power supply), a red LED for the click signal and a green LED for the power supply light up on the control unit to indicate that the device is working properly. Control device displays. The functionality of the click generator can be checked with a commercially available bat detector, as the click sounds are not audible to the human ear. You may hear a soft, interval-like ticking.

If you should question the functionality or the flawless operation of the click generator at a later point in time, please contact us.
