Product: Sera Multifil 350 - external filter for special materials
Special media filter for connection to pumps or external filters
The unpowered filter saves energy as it is connected to an existing pump for directing water back into the aquarium or to a bypass with a 16 mm (internal diameter) hose. It can hold up to 350 ml (11.8 fl.oz.) of filter media, which are kept in position between perforated plates so water will flow through optimally. Screwing off the bottom part allows easy access to the filter media, which can be quickly replaced this way. De-aeration is done with an air valve included with the kit.
Filter with holder plate, 2 suction holders, air vent valve, air vent hose 20 cm (8 in.), 1 spare seal
The Sera Multifil 350 is possibly one Sera aquarium product which could see widespread adoption by the saltwater crowd moreso than the freshwater people. The Multifil 350 is clealry built from the design of their Sera Flore CO2 Reactorwith its inlet and outlet hose and screw on lid. The simple yet sturdy construction of the molded acrylic body is actually attractive and includes a built-in docking mount for easy removal from the aquarium sump or stand.
Whereas almost all aquarium media reactors are like really large, the Sera multifil 350 is actually an appropriate size for smaller tanks; it can hold up to 380 ml of media which is jsut about right for 50 gallon aquariums with carbon use or 100 gallons with GFO.
