Arka myAQUA Multifilter 500 ml is ideal as an extension for many commercially available osmosis systems, such as our Arka myAQUA 190/380, or for connection to a pump. The multifilter offers space for 500 ml of filter material, such as mixed bed resin, phosphate absorber, silicate absorber, activated carbon, zeolite, bio-pellets, and much more. Thanks to its integrated filter screen and filter sponges, the Arka myAQUA Multifilter 500 ml effectively prevents any abrasion of the filter material into the aquarium. The delivery includes the hose and connectors, as well as a wall mount. Dimensions: length: approx. 32.5 cm, diameter: approx. 6 cm.
