Online Discount OASE Indoor Aquatics Biostyle 20 Fish Filter, Dark Blue

The OASE Indoor Aquatics BioStyle 20 Fish Filter helps to efficiently clean your aquarium water. Suitable for marine and freshwater aquariums, it features one disposable, multi-stage filter cartridge and a biological filter foam. The multi-stage cartridge includes a filter foam, three chemical media mix and filter fleece to trap debris and waste and create surface area for beneficial bacteria. The filter media mix removes odors, impurities and harmful nutrients from the water, while the fleece traps extremely fine debris for a water polishing effect. An adjustable leveler makes it easy to secure the filter onto the aquarium rim, and a cleaning indicator makes it easy to see when it’s time to change the filter cartridge.
