I ordered this filter, because my other external filter has given up the ghost. Ordered on the off chance that this model fits into my Fluval Edge Hagen Aquarium, (yes it fits in), but sorely disappointed by the quality! Poor workmanship and a very noisy pump. Not suitable for the area in a living room or office. The product may be functional for use in the basement. The supplied sponge is not really to use in my opinion. Artificial, plastic smell, lousy material. Because you're afraid to be stocking the aquarium! Another point is the strength of the device: Very high water flow: On the one hand well, thus a lot can be filtered, on the other hand very strong circulation in the pelvis. Not all types like this .. Product declined detour Los.
