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.

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.

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.
