Top Fin Mini Gravel Vacuum 56" Hose, 17" cylinder

Small but gets the job done.

I didn't buy mine off of Amazon, but rather at PetSmart, and I love this vac, it works great, although they now make the Top Fin vacs with a hand-pump, but this one works too. I use mine for my 10 gallon tank, my 2.5 gallon, and both my sisters 3 gallons (that I take care of). This one comes with a bucket clip to keep the hose from spraying water every where!
