The Delta from UNS is an external filter that is characterized by its durable construction, powerful technology and dynamic performance. It offers efficient filtration and reliable circulation in medium to large aquariums. Particularly noteworthy is the low-noise operation of this filter, which makes it ideal for rooms where quiet performance is desired. Thanks to the cooperation with Aquario, the filter comes with a Neo Flow In-/Outflow Set Standard V.2 and Neo Media Premium M Pure. Special mention should be made of the design of the filter chamber, which enables particularly flexible filling of the supplied media. The individual elements, which include three containers for the filter media, are stacked on top of each other like a tower. The enclosed media Green Sponge, Black Sponge and Aquario Neo Media can then be inserted into the containers as required.
The easy maintenance of the 3-stage filtration chamber, the powerful pump and the flexible media selection make the Delta external filter an indispensable element for every aquarium.
