Yes it works
after finding the right adapter it's great. Its works well in our 150 gallon fish tank. Now I can clean the gravel without changing water draining  75 gallons of water and filling it back up again is a lot and it really does not clean the gravel that well. The only other thing is the bags is real small but I can deal with that.  If any one wants to buy the right adapter it is Zjchao 3v 1A AC to DC adapter 5.5/2.1 mm
