Resun BioClear Power Filter 300 4-in-1 Internal Filter

The Resun BioClear Power Filter 300 is an internal aquarium filter that combines mechanical, chemical and biological filtration with water aeration in one housing.

Mechanical cleaning is done by a sponge and two-layer filter pads. According to the manufacturer, the activated carbon removes impurities and odour from the water, and the ceramic rings give beneficial bacteria a large surface to grow on. The replaceable filter cartridge makes maintenance simpler. For the outlet, you can choose between a spray bar and a jet nozzle.

Adjust the pump output with the knob on top of the filter and direct the flow to suit the aquarium. The aeration strength is set with the valve on the air tube.

The set includes a sponge, bio-ceramics, activated carbon, a fibre filter medium, a spray bar, a jet nozzle and an air tube with a valve.
