Powerful hang-on filter with mechanical-biological cleaning. Suitable for freshwater and saltwater aquariums up to a maximum of 180 liters. Easy to install thanks to the flexibly adjustable spacer. The water flow rate is infinitely adjustable, and the operation is pleasantly quiet. An indicator shows when it's time to clean or replace the filter cartridge. The BioStyle hang-on filter is a straightforward filtering alternative: it simply hangs on the edge of the aquarium and does not require a hose connection for operation. The elegantly designed dark blue exterior is easy to clean from the outside - without wet hands. The BioStyle filter operates in two stages: biological and mechanical cleaning ensure long intervals between maintenance and low cleaning effort.
