Eden 522 Aquarium FishTank External Filter 300L 1000L/H + Heater300w built-in

Supplied complete with intake system, hoses and connecting elbows and with a spray-bar outlet for better surface oxygen exchange at the water surface (or you can use the flow diverter which can be oriented as required), the 501 external filter is a professional canister and can be installed in both fresh and marine tanks.

Its unique and reduced design allow an easy installation at the side or behind the tank in case of very reduced space available in small houses or flats.

The motor is completely sealed and thermal-protected, developed with the well-known EDEN quietness during operation, along with reliability, lower power consumption, thus offering any fish keeper the ideal performance of a proper filtration for the tank.

The hose removal device and the simple opening system of the filter head, along with the childproof lock by means of safety buttons make the filter among the most reliable and safe on the marketplace of canisters.

Equipped with a doubled filtering system and easily priming by filling the cap on the filter head, the 501 is extremely silent by means of rubber feet which also offer additional stability and avoid direct contact with surfaces where it is located.

A compact and room-saving design make this filter the most wanted and used by expert fish keepers worldwide.
