## Features

- OPTIMIZED FLOW & FILTRATION FOR CRYSTAL CLEAR WATER – The next generation of BioMaster has updated features for increased performance. A sealed 4-stage filtration path with multi-density foams, Hel-X Biomedia, and activated carbon delivers superior water clarity for freshwater and saltwater tanks.
- THE MOST CONVENIENT CANISTER FILTER ON THE MARKET – The BioMaster's innovative EasyClean pre-filter module can be removed separately from the rest of the filter. This makes maintenance fast and simple. It also increases filter efficiency and extends the life of main filter foams.

- NO-MESS MAINTENANCE – Designed with safety locks on the handle, pre-filter, and aquastop to avoid spills during maintenance. The aquastop is detachable for easy movement of the filter without affecting the tubing setup.
- RELIABLE & BACKED BY WARRANTY – Made in Italy, with German engineering from OASE and backed by a 4-year warranty (3 + 1 year with online registration). Includes all the necessary fittings for your setup: curved inlet and outlet tubes, inlet strainer, water outlet nozzle, modular spray bar with flow control attachment, tubing, heater, heater adapter, and 6 ft. power cords (one cord for filter, one cord for heater).
