The Aqua One ClearView 300 Hang On Filter clips onto the back of your aquarium, keeping filtration out of the tank and saving valuable space. It’s ideal for planted aquariums and any setup where an internal filter would take up too much room.

It combines filter wool, activated carbon and a bio grid in one compact unit for mechanical, chemical and biological filtration. The built-in powerhead delivers up to 300 L/h, and a flow regulator lets you adjust the flow to suit your fish. Water returning over the lip of the filter keeps the surface moving, which helps oxygen exchange.

Please note: Always unplug the filter before maintenance. Make sure the water level reaches the filter intake before switching on. Rinse media in old tank water, not tap water, to protect beneficial bacteria.
