Aquarium Gravel Cleaner Syphon Siphon Vacuum Fish Tank

I bought this because I wanted to clean my little 10 gallon aquarium. I've used it twice now, and while it added water very well, I did not find it at all satisfactory in siphoning out to clean the gravel. And by the way, I am an experienced aquarium owner. Since the main thing I wanted it for was cleaning, it was a disappointment to me. Hence, 2 stars.
