Aqua One ClearView 500 Filter
29028Hang on filters are designed to be clipped onto the back
of your aquarium. They are ideal for garden aquariums
or any other way, where a submersible filter would take
up too much space. They provide very high levels of
Flow regulator which can be used to adjust the water flow through the filter.
The combination of wool, carbon and bio grid provides a complete and very
compact filtration solution.http://www.youtube.com/watch?v=2imp_a3ld60
