    SUMMARY:
    According to the invention a means for inhibiting the growth of algae and for promoting the growth of higher marsh and aquatic plants in water containing the trace elements iron, manganese, zinc, copper, boron, sulfur and molybdenum is provided according to protection claim 1. Preferred embodiments thereof can be found in the dependent claims. Furthermore, the use of these trace elements in an agent for inhibiting algae growth and for promoting the growth of higher swamp and aquatic plants in water is described, and the use of tetrasodium iminodisuccinate in agents for inhibiting algal growth and for promoting the growth of higher swamp and aquatic plants in water.
    STATE OF THE ART:
    Swimming ponds, bathing ponds and natural pools, like other artificial pond systems (e.g. the majority of garden ponds), are closed systems with no inflow or outflow from outside or contact with the groundwater; In contrast to normal garden ponds, they are designed for use as swimming and bathing water.
    In contrast to chlorinated swimming pools and pools, swimming ponds, bathing ponds and natural pools are based on the principle of biological clarification via microorganisms and marsh and aquatic plants used. Such pond systems, such as natural inland waters, also allow the existence of many animal species including a wide variety of insects, crustaceans and amphibians. There are different types of such systems, which differ in particular through the different use of technical pump and filter systems. In such systems, water loss due to evaporation is compensated for by rainwater or targeted supply from tap water or other sources.
    The function of swimming ponds, bathing ponds and natural pools is only guaranteed with a low to moderate content of macronutrients, especially phosphorus and nitrogen. One speaks of an "oligotrophic" body of water.
    If these nutrients are not available at all, the plants used cannot grow and there is a lack of, among other things. the nutrient basis for animal pond dwellers. If the macronutrient content is too high, excessive undesirable growth of floating and filamentous algae and biofilms usually occurs.
    The concept underlying swimming ponds, bathing ponds and natural pools means that in the first years after creation, just like every year at the beginning of the vegetation period, a biological balance with low nutrient content must be established independently. Once the planting is dense enough and the swamp and underwater plants used remove enough nutrients for their growth from the water, the growth of floating and filamentous algae should be effectively suppressed. This should entail a relatively low maintenance and cleaning effort.
    The requirement for the desired function of swimming ponds, bathing ponds and natural pools is always the observance of certain conditions in order to ensure the necessary low concentration of macronutrients, in particular phosphate and nitrate. This includes the exclusive supply of low-phosphate and low-nitrate water, the avoidance of unnecessary new entries of macronutrients and the removal of enriched nutrients / 15

    In practice, however, even meticulous compliance with the above. Conditions often fail to achieve the desired result: The plants used either do not grow at all, or at least the hoped-for abundant growth of higher pond plants is lacking. Instead, floating, thread and lubricating algae take over, the film in the swimming area is covered with thick biofilms, and the swimming pond looks anything but inviting.
    ALREADY AVAILABLE METHODS FOR THE REMOVAL OF THREADED ALGAE, LUBRICANT ALGAE AND ORGANIC FILMS:
    Floating algae that cloud the water can, in contrast to filamentous algae, usually be combated relatively effectively, e.g. through suitable filter systems or UV treatment. Thread algae lack similarly effective and at the same time unproblematic or low-cost methods. With excessive algae growth in swimming ponds, bathing ponds, natural pools and artificial pond systems, the following measures have so far been possible, although they have all disadvantages and limitations:
    1) Mechanical aids are available for the complex removal of thread algae, e.g. Pond vacuum cleaners or electric pond scrubbers, however, such methods are only of limited effectiveness, remove thread algae growth incompletely and are extremely time-consuming.
    2) Another method offered to combat floating algae and filamentous algae is an ionization process in which copper and silver ions are released from electrodes. Some of the released ions enter the pool with the water flowing through them, where they also develop their bacterial and algae-killing effects.
    The heavy metal copper is essential in very low concentrations as a trace element for plants. Copper, just like silver, is toxic to many microorganisms in the higher concentrations required in the ionization process. The toxic effect of copper arises from the fact that copper ions bind to thiol groups of proteins and peroxidize lipids of the cell membrane, which leads to the formation of free radicals that damage the DNA and cell membranes. This effect of higher copper concentrations is not limited to algae, but also affects higher plants and animal organisms. It has long been known from aquaristics that copper is highly toxic to shrimp. There is also clear evidence that there are long-term toxic effects even in vertebrates due to the rather high copper concentrations used in the ionization process (Hanns-J. Krause, 2009, Handbuch Aquarienwasser).
    The copper and silver dissolved in the water (just like chlorine in conventional pools) can, according to current knowledge, be considered harmless to humans. On the other hand, due to the high toxicity to microorganisms and crustaceans, and the associated severe damage or even complete destruction of the microbiocenosis (the entirety of the microbial community in a habitat), you can no longer be sure of a biological intact at a swimming pond with high copper concentrations in the water Waters talk. A basic principle of a swimming pond, the biological cleaning when flowing through the bottom can no longer work here.
    3) Chemical substances are also used which kill algae or at least inhibit algae growth. These include classic algicides, i.e. chemicals from the group of biocides, for which no damage to the human organism is detectable in the concentration range used. Biocidal products are generally subject to the Biocidal Products Regulation (EU) No. 528/2012. Article 3 (1a) defines biocidal products as “any substance or mixture of substances that
    2.15
    AT15 708U1 2018-04-15 Austrian
    Patent Office is intended to destroy, deter, render harmless, prevent their effects or otherwise combat harmful organisms in a manner other than mere physical or mechanical action. A biocide contained in the majority of algae preparations and often used there together with high concentrations of copper sulfate (for adverse effects see above under 2) is e.g. Monolinuron, a urea derivative. Monolinuron inhibits photosynthesis and is also used as a herbicide in agriculture. In addition, many microorganisms that are important for the biological balance of the swimming pond are also killed. Significantly, monolinuron is therefore classified in water hazard class 3 (WGK) 3, which is highly hazardous to water. It carries the hazardous substance labels Xn = harmful to health and N = dangerous to the environment. In general, with algicides that are primarily directed against algae as lower plants, an effect on higher plants in the pond can hardly be excluded. For most (ecologically thinking) swimming pond owners, such chemicals that are potentially harmful to health and the environment can of course not be the method of choice.
    4) Other chemical dyes (e.g. Aquashade or Dyofix) also inhibit filamentous algae, but by definition they are not algicides because they have a physical mechanism of action. Unfortunately, such agents lead to a clear unnatural coloring of the pond water.
    In the end, the swimming pond owner usually only has the choice between ecologically questionable or even toxic algae killers and the laborious scrubbing of biofilms and algae from the walls of the swimming area. Landing nets and sludge vacuums must be used in the regeneration area to vacuum and remove the thread algae in order to keep the bathing pond reasonably presentable.
    Water in swimming ponds usually contains sufficient usable nitrogen and phosphate by entry from the air. In addition, phosphate is primarily enriched via feed water, leaves, flowers and pollen, as well as through release from the rocks that are introduced and are often unsuitable in practice.
    Most swimming ponds, however, as closed waters without inflow or groundwater exchange from the beginning, or at the latest after a few years, from a lack of individual trace elements, which do not reach the pond in sufficient quantities via atmospheric deposition. However, higher aquatic plants can only grow abundantly if all necessary trace elements are sufficiently available. If only one trace element is missing, this inhibits plant growth, the algae are not adequately deprived of phosphate as a basis of life and excessive algae growth occurs.
    For lubricating and filamentous algae it is further aggravated that, unlike in the mostly cloudy natural inland waters or normal garden ponds, filamentous algae in swimming ponds, bathing ponds and natural pools often have very good lighting conditions and therefore the best growing conditions due to the very clear water find. In addition, unlike floating algae, lubricating and thread algae have relatively few predators.
    A crucial problem for the functioning of swimming ponds is that the mostly considerable persistent inputs of phosphates and nitrogen sources are largely unchangeable. In many swimming ponds, the majority of the available nitrogen and phosphate simply comes from the atmosphere. The atmospheric nitrogen input in most, often densely populated and industrialized, regions of Germany is around 25kg / ha and year (source: Lower Saxony State Office for Mining, Energy and Geology, 2014). In the case of phosphates, too, there is a considerable entry via the air. Although the entry here is about a factor 10 lower than that of nitrogen, it is also significant.
    A further and often not considered or underestimated source is the source

    AT15 708U1 2018-04-15 Austrian patent office
    Construction brought in natural stone. It is e.g. meanwhile, it is known that sandstone - just like lava rock or basalt - can have a greatly increased phosphate content. Since the exchange of such rocks is usually not practical, this entry must usually also be viewed as unchangeable.
    Decisive for the development of filamentous algae seems to be the starting concentration of phosphates immediately after the swimming pond has been created or at the beginning of the season, just like the density of the planting with higher swamp and aquatic plants and their growth. If the resident swamp and aquatic plants find all the necessary foundations for rapid growth in the spring and there are no massive excesses of phosphate, they are able to efficiently reduce the phosphate content to such an extent that the thread algae are the basis for excessive reproduction is taken. Interestingly, most filamentous algae seem to need higher phosphate levels (> 0.01 mg / l) as a nutrient base than higher swamp and aquatic plants. This means that in a swimming pond or natural pool with abundant growth in higher marsh and aquatic plants, the thread algae are permanently deprived of the growth basis.
    In many swimming ponds, however, the abundant growth in higher marsh and aquatic plants is limited by a lack of individual trace elements. This means that less macro nutrients are used, which in turn provides an excellent basis for the growth of algae and biofilms.
    DESCRIPTION OF THE INVENTION:
    To solve the problem described above, a new concept for reducing excessive algae growth in swimming ponds, bathing ponds and natural pools based on the addition of defined trace elements with high plant availability was developed.
    About the targeted supply of all necessary and often missing in swimming ponds microelements, without simultaneous supply of phosphate and nitrate, the trace element concentrate described leads to abundant plant growth and thereby massively inhibits the multiplication of unwanted floating and thread algae.
    Based on complex optimization work, the trace element concentrate described now contains a balanced composition of trace elements which is specially tailored to swamp and aquatic plants in swimming ponds, bathing ponds and natural pools. This optimized composition is more extensive than typical trace element fertilizers in aquaristics or for garden ponds with fish stock. It also differs significantly from these in the composition itself. While in aquariums and garden ponds a number of trace elements are usually sufficiently supplied by feeding, this is not the case in swimming ponds. In many cases, additional trace elements must be made available here. The dosage of trace elements, on the other hand, is generally relatively low and thus takes account of the situation in oligotrophic waters with a relatively low macronutrient content.
    The composition and formulation of the trace element concentrate described here for the inhibition of algae growth in swimming ponds, bathing ponds, natural pools and artificial pond systems represents a basic formulation which can be customized to the specific nutrient situation in individual swimming ponds.
    Since there may be a shortage of individual trace elements, depending on the soil and rock introduced, even in newly created swimming ponds, the administration of the trace element concentrate can be useful even in new pond systems so that pond plants used are already in the important growth phase no nutrient is lacking.
    Another crucial feature of the trace element concentrate described for use in swimming ponds is the excellent plant availability of the

    AT15 708U1 2018-04-15 Austrian
    Patent office contain trace elements with simultaneous complete biological usability or degradability of all components. In conventional plant fertilizers for agriculture, horticulture, for growing houseplants or for aquariums, trace elements are complexed with chemical complexing agents such as EDTA (ethylenediaminetetraacetate), DTPA (diethylenetriamine-pentaacetic acid) or EDDHA (ethylenediamine-dihydroxyphenylacetic acid), which are not biodegradable made available to plants. In the closed swimming pond designed as bathing water, the continuous use of such fertilizers would lead to a progressive accumulation of these chemicals and thus ultimately probably also to disturbances in the biological systems. For this reason and in view of the special ecological requirements in swimming ponds, metal ions in the trace element concentrate described above are completely biodegradable complexing agents, e.g. N- (1,2-dicarboxyethyl) aspartic acid or its salts tetrasodium iminodisuccinate (also: iminodisuccinate tetrasodium salt, IDS or IDHA), complexed.
    [0029] Other examples of suitable biodegradable chelators are gluconates and lignosulfonates. Also mentioned are ethylenediaminedisuccinic acid (EDDS), nitrilotriacetic acid (NTA), methylglycinediacetic acid (MGDA), L-glutamic acid Ν, Ν-diacetic acid (GLDA), ethylenediamine-N, N'-diglutaric acid (EDDG) and ethylenediamine- N, N'-dimalonic acid (EDDM), 3-hydroxy-2,2-iminodisuccinic acid (HIDS), 2-hydroxyethyliminodiacetic acid (HEIDA), also known as ethanol diglycinic acid (EDG), pyridine-2,6-dicarboxilic acid (PDA), also known as dipicolinic acid.
    It is crucial that the trace element concentrate is used as much as possible during the entire growth phase (normally April to September inclusive). The aim of the application is to achieve a stable biological balance with lush growth of swamp and underwater plants, which removes the excess phosphate and nitrate from the pond water and thus the uncontrolled proliferation of algae.
    ADVANTAGES OF THE APPLICATION OF THE DESCRIBED TRACE ELEMENT CONCENTRATE IN COMPARISON TO PREVIOUS METHODS OF ALGAE CONTROL:
    The trace element concentrate, unlike the preparations used hitherto, is not an algicide which merely kills algae but does not remove the cause of the excessive algae growth.
    · The trace element concentrate sustainably minimizes the multiplication of floating and filamentous algae by removing the nutrient base from the algae by promoting the growth of higher plants used.
    As a side effect, the trace element concentrate also promotes the very desirable abundant growth of underwater and swamp plants in swimming ponds, bathing ponds and natural pools.
    · By using the trace element concentrate, the use of ecologically questionable copper and biocide-containing preparations is avoided. When used in swimming ponds, bathing ponds and natural pools, the avoidance of potentially toxic effects on organisms other than algae and of potentially harmful effects of the above-mentioned. Highlight substances in contact with skin or if the pond / pool water is swallowed.
    · In contrast to many other commercially available aquatic plant fertilizers, the trace element concentrate is phosphate and nitrate-free and contains a balanced combination of trace elements with excellent plant availability that is specially optimized for swimming ponds with their special requirements as oligotrophic waters.
    The trace element concentrate contains, unlike commercially available trace element fertilizer solutions for aquariums, horticulture or agriculture, no chemical complexing agents such as EDTA or EDDHMA, which are not biodegradable and

    AT15 708U1 2018-04-15 Austrian
    Patent office continues to accumulate in the pond water. The exclusive use of biodegradable organic substances takes into account the use in swimming and bathing water, the ecological character of swimming ponds and the widespread customer request for a chemically unpolluted natural water.
    The trace element concentrate described thus offers a sustainable solution with which a lush growth of swamp and underwater plants can be achieved in a natural manner, without unnecessary use of chemicals, instead of excessive propagation of floating and filamentous algae. The concentrate minimizes the excessive multiplication of algae and biofilms and thus considerably reduces the maintenance effort for swimming ponds.

Preferred embodiments thereof can be found in the dependent claims. Furthermore, the use of these trace elements in an agent for inhibiting algae growth and for promoting the growth of higher swamp and aquatic plants in water is described, and the use of tetranatium iminodisuccinate in agents for inhibiting algae growth and for promoting the growth of higher swamp and aquatic plants in water.
    [0039] In a preferred embodiment, the waters are swimming ponds, bathing ponds or natural pools.
    [0040] The agents can be provided in solid or liquid form. The agents are usually provided as concentrates as a mixture. Usually the concentrates are at least 100 times more concentrated than the concentration thereof in the water when in use. Suitable concentrates are in particular those which are concentrated 10,000 times up to 10,000,000 times.
    [0041] This concentrate can be a liquid concentrate in which the trace elements are present in solution. Alternatively, the agent can be in granular form as a concentrate.
    In a particularly suitable embodiment, the agent is in the form of granules or as a liquid concentrate which is concentrated> 1 million times the concentration in water.
    The trace elements are usually present as dissolved salts in the liquid concentrate or as salts in the granules. The granulate is produced by known granulation processes, if necessary with fillers.
    The agent can be completely mixed or in several components that are mixed before or during use.
    The trace elements in the water are preferably in a range of:
