Excellent gravel cleaner for small aquariums

Have a 38L small aquarium and change the water makes the gravel cleaner very good services:
- Water through the pump sucked (ekeliges suction by mouth omitted)
- Through the narrow suction pipe can work very well in small aquariums and it is also useful if clean water is returned to the aquarium because it draws water to stable from the last corner of the bucket of water and does not slip
- Clamp the hose also guarantees clean working

With fine Garnelenkies I had no problems so far, it is purely the sludge sucked. While it is true that if you accidentally sucks larger pieces / plant remains / adhesive along gravel, the valve is blocked, but that is in the nature of things and can not be accused of the valve. Then you take up from the Ansaugroh and blows the valve once.

Bin after repeated use is still very satisfied. It broke anything and the service is consistently good.
