Review on Aqueon Quietflow Internal Filter Gallon Fish & Aquatic Pets made as Aquarium Pumps & Filters by Denise Harmeyer

Bought this filter to help my other filter clean my 55 gallon tank. This dinner is very similar in that it can be immersed in water. At first there were bottom suction cups and a hanger at the top, but the top of the aquarium would not close. So put on the suction cups (included) and close the lid of the aquarium. The only reason I gave it 4 stars is because it looked like it would either be used or sent back. Dirty on the outside and the box looked like it was open from the bottom. Would return it if unit doesn't work but it worked. So far I am satisfied with this device.
