No use for small or densely stocked aquariums

When ordering, I was actually quite happy that I can get such a favorable gravel washer. When I held it in my hand, I got a little doubt whether this would also work well. In use, I was really disappointed.

1. For small aquariums the cylinder is just too big. Enter letting the water in the cylinder and the hose is simply impractical
2. The tube is just too short. If the aquarium is not on the ground, and that is in most cases, so you need another tube, which must then be coupled.
3. The inside diameter of the tube is unfavorable. Unfortunately, the couple with my previous hose is not.

Conclusion: relatively inexpensive, but for my aquarium (width 1 meter) is not suitable this pool cleaner.
