The pump works great, quiet. When using a high aquarium you need to extend the suction pipe with a hose. I extended it with the pump hose and it became extra. Aquarium 110 liters 👍

Outside pump vibrates a bit more than standard in-cannister pumps but not super noticably. Very powerful pump, great filter, definitely worth the money. Quality on the level of name brands.

Sensational. It filters very quickly and very well. I assembled it with the water inlet at the top and the outlet at the motor. It’s difficult to get it working at first (for example, getting water to fill everything), but it filters very well. I assembled it (from bottom to top): activated carbon, biological media, perlon, and black foam. I preferred not to use what comes with it because I think this assembly is better.
