Accessories and spare parts - make your filtration system complete In addition to the main components, we offer all kinds of additional equipment and components like tanks, aeration equipment, ozone reactors, and Artemia breeding stations for live food production. If needed, we can produce a complete filter system for your application. The advantages include: - All components are compatible and fit together - guaranteed! - Top quality components - Rapid delivery of all components means no construction delays. All of these factors save trouble, time and money.
Skimmers - Whisk for clean water Skimmers remove proteins and lipids along with the associated bacteria, algae, and many other adhering substances from water. The method is relatively simple. Very fine air bubbles are released into the waste water, producing a foam. This foam gathers at the surface and can be easily removed along with the adhering organic substances. This efficient technique has been used in saltwater filtration for decades. For many years, this technique was not as efficient as desired for fresh water filtration - but thanks to new bubbling technologies, this has changed. Our Berlin and Swat skimmers were among the first fresh water skimmers on the market with performance comparable to that of saltwater skimmers. Furthermore, skimmers also enrich the water with oxygen and stabilize the pH. By adding ozone, you can use the skimmer for efficient disinfection of the water and reduce the bacteria load. 
Our filters for aquaria – made for crystal clear water and healthy animals It is a challenge and lots of work to keep large aquaria, especially saltwater aquaria clean and the animals in good condition. Our filter technology is reliable and robust. They are easy to operate and efficient. Because even a short malfunction of the filter system can cause the loss of expensive animals, it is important to invest in quality. Some of our skimmers are in use for more than 20 years now. It is the persistence of our products, which pays for itself. This is our promise to our customers. For more details, click on the product. All products as well as the technical data can be found in our catalog.
