For cleaning or filtering aquarium water, a wide variety of materials have been used as Filter media such as coal, peat, glass floss and others. m. - except those of ceramic origin - used. However, these filter media have been found to be disadvantageous insofar as they only after a certain Start-up time, often only after days, are able to filter cleanly. For disinfecting aquarium water and control of fish parasites or diseases have hitherto been suitable salt and dye preparations used without filtering, the disinfectant should remain effective. However, such preparations have in many cases either by the salt enrichment in the Aquarium water has a detrimental effect on fish and plants, or the dyes prevent the Assimilation.

According to the invention, the above-described deficiencies are now in a process in the aquarium filtration eliminated. For this purpose, fine-pored ceramic materials such. B. raw china, Clay or artificial pumice stone in the form of thin slabs or granular granules with for that Aquarium biology prepared suitable active substances. Such active substances must be in the aquarium water insoluble and durable connected to the ceramic filter medium as well as the disinfection suffice. There are especially suitable metal oxides in question, such as. B. silver oxide Ag20. But colloidal metals or chemical substances that are only sparingly soluble in water can also be used come when they produce the so-called oligodynamic effect, through which with targeted dosage the harmful microorganisms to be combated (parasites, protozoa, bacteria, blue-green algae) be destroyed without damaging macro-organisms such as fish and plants.

According to various inventions, oligodynamic means, such as. B. iron (III) oxide, for the oxidation of organic substances when cleaning drinking and industrial water, mostly with the additional use of ozone and other oxidizing substances. Included It is not the oligodynamically active substances (or contact agents) that count as inventions, but theirs technical application, which is why these inventions and the contact means selected there are neither technical can still be used biochemically for the aquarium environment.

The aquarium water is usually brought into circulation with the air flow generated by special aquarium aerators and, when filtering through ceramic bodies, with contact means

Filter chambers passed with appropriate filter media. The aquarium water is now according to the invention passed through a ceramic medium with contact means in a filter housing or a filter chamber. In many experiments it was found that with smaller amounts of water, i.e. in smaller aquariums, already the contact (contact) of the water flowing past with the contact agent for disinfection enough. If you do not use a filter, you can use one made of artificial pumice stone existing air vents, which have been prepared with suitable contact means, smaller quantities Completely disinfect the aquarium water.

The fight against cloudy aquarium water through permanent fine filtering, for example with the ones described Filter plates in aquarium filters, or the simultaneous disinfection with almost non-consumable Contact materials or their use in connection with outflow stones were in the aquarium hobby hitherto unknown and undescribed. The only distantly related field of water purification and -processing is more present because of the fundamentally different and therefore not appropriate objectives Invention extra excluded.

There are around three forms of ceramic media with contact media that can be considered for this new method: Firstly, air stones of any shape, secondly, any granular filter medium Grain size (granulate) and thirdly, fine-pored filter plates of any dimensions.

A very effective combination of the three forms mentioned can be achieved by placing them in a suitable housing and is shown schematically in the drawing as an aquarium filter, where α is the air stone, b is the filter granulate and c is the filter plate. The arrows show the water cycle in the aquarium created by the air bubble in the air stone.

The advantage of this invention is firstly in the possibility of immediate fine filtering through the fine-pored ceramic medium in plate form (filter plates), secondly, because of the large space savings thin filter plates in contrast to the thick layers of previous filter media, thirdly in the possibility of optionally on the one hand with filtering, simultaneous disinfection and control of fish diseases to achieve through the contact means insoluble with the filter medium, on the other hand only with Aeration with a prepared, air-porous, ceramic stone (air stone) in small aquariums to achieve the same disinfecting effect, and fourthly, that the bacteria and dirt repel Properties of the contact means prevent it from growing together with the filter medium, as a result of which the cleaning of the pores (e.g. the filter plates) is made much easier and the service life of the filter medium is increased is increased.
