Use of Ozone in Aquariums
Ozone is an innovative and effective solution for keeping your aquarium water clean, crystal-clear and free from bacteria. Thanks to its high oxidising power, it removes organic impurities, improves oxygenation and helps to create a healthier environment for your fish.
Ideal for marine and freshwater aquariums, ozone optimises water quality without adding chemicals.

Are you having problems with the water quality in your aquarium?
The use of ozone in large-volume aquariums is the most advanced solution for tackling waterborne infections and drastically reducing mortality rates amongst sensitive species. Acting as a broad-spectrum biocide, ozone instantly eliminates viruses, bacteria and parasites without leaving any toxic residues. This helps to maintain a biologically safe and healthy ecosystem, reducing reliance on chemicals and medicines that often cause stress to the fish and disrupt the balance of the aquarium.
One of the most notable visual and operational benefits is the complete elimination of turbidity and suspended microalgae. Ozone oxidises the organic matter and colloidal compounds that cloud the water, achieving crystal-clear transparency that enhances the visitor experience. Furthermore, by removing excess organic load and microalgae, the formation of deposits is prevented and an aesthetically impeccable environment is maintained with minimal upkeep.
Finally, the deployment of ZonoSistem systems ensures optimal levels of dissolved oxygen, a critical factor for the vitality of marine and freshwater fauna. Ozone not only purifies the water, but as it breaks down it turns into pure oxygen, improving the animals’ respiration and metabolism. By integrating this technology into your treatment plant, you will achieve superior performance from the filtration system, healthier water and a chemical-free environment, whilst meeting the highest standards of animal welfare.

Benefits of using ozone in aquariums
Maximum disinfection with no residue
Ozone is used worldwide to disinfect aquarium water, thanks to its powerful ability to eliminate viruses, bacteria, fungi and moulds, with the advantage that it leaves no residue and does not accumulate in living organisms. An essential tool for reducing mortality
Improves water quality
Ozone is an excellent water treatment agent for aquariums; it oxidises and breaks down organic and inorganic matter, and reduces COD, BOD, SS, SD, turbidity, colour, odour and taste. It improves flocculation, coagulation and filtration in the treatment system. It removes toxins and heavy metals. It also provides an extra supply of dissolved oxygen, stimulating the fish’s metabolism and growth.
A comprehensive view for the viewer
Ozone is the most advanced technology on the market for achieving unrivalled clarity in water. By removing organic compounds and suspended particles, it significantly improves transparency, offering a crystal-clear and spectacular view through the glass.
No manual labour, fully automatic
The system automatically generates and injects ozone into the tank, without the need for manual labour. It simply needs to be connected to the tank and a power socket.
No chemical storage
Ozone is generated on site and applied immediately, so it does not require the storage or handling of chemicals, eliminates the need for transport and reduces the carbon footprint.
Biocide recognised by ECHA
Ozone is included on the European Chemicals Agency’s (ECHA) list of biocides, and ZonoSistem has all the necessary documentation for its proper authorisation and use

ZonoSistem case studies in ozone treatment for aquariums
Ozono para aquarium, España
Este proyecto incluye un generador de ozono gama industrial, modelo GRZO120 que inyecta ozono tras la filtración del agua. El sistema garantiza la desinfección del agua enviada a las piscinas con animales. Se controla el ORP del retorno y de la impulsión, se registra y se controla remotamente.
Sistema de ozono para aquarium, Portugal
El proyecto incluye un sistema de ozono profesional HIDRO VT GZO40 que trata el caudal total de la recirculación del acuario, posteriormente se elimina ozono con radiación UV y se envía a las piscinas donde los visitantes admiran las especies acuáticas marinas.
Ozono para agua de cuarentena de acuario, España
El proyecto incluye un sistema profesional HIDRO V GZO20 que desinfecta el agua procedente de los tanques de cuarentena. Este agua elimina la peligrosidad biológica del agua antes de su vertido de nuevo al mar. Además, el ozono oxida compuestos como los medicamentos y toxinas excretadas al medio acuático.
Sistema de ozono para aquarium, España
El proyecto incluye un sistema de ozono de 80g/h que garantiza la desinfección del agua enviada al acuario. El sistema pertenece a la gama industrial, refrigerado por agua y autosuficiente.

This project involves a professional-grade ozone generator with a capacity of 115g/h, which injects ozone into four mixing systems located in four different aquatic environments, all of which are freshwater. Each injection and mixing system controls the desired ORP level in the water within its respective circuit.
Frequently asked questions about the use of ozone in aquariums
Ozone oxidises dissolved organic matter and breaks down tannins and microalgae, which often give the water a yellowish or cloudy appearance. By clumping together microscopic particles (micro-flocculation), it enables the filtration system to retain them, resulting in exceptional clarity that improves visibility of the species.
Yes, provided it is monitored using redox (ORP) measuring equipment. The ZonoSistem system allows the injection of ozone to be automated in order to maintain precise disinfection levels without posing any risk to the animals. By eliminating pathogens and increasing dissolved oxygen, it creates a much more stable and healthy environment than that achieved using chemicals alone.
Our equipment is designed for continuous industrial operation with minimal maintenance. It only requires periodic checks of the air filtration elements and the generation cells. As the system generates the gas on-site, this eliminates the risks and costs associated with the transport and storage of hazardous chemicals.
