"I just received my cleaner and immediately began using it. It took a second to read through the directions to figure it out exactly but it really wasnt difficult at all.
Once you figure it out ( Like I said, very easy) it was a BREEZE to clean the gravel rocks. I then filled up the tank again JUST as easily and with NO mess and NO running back and forthe to the tub or sink with buckets. You just simply turn a switch.
If you have a fish tank or are thinking of getting one ( especially a larger sized one -over 20 gallons or so) then this things is a MUST have. TRUST me you will thank me..
The hose and connector pieces are also durable and well made.. it isnt a cheapy made product. Buy the tank, the fish and your NEXT purchase should be THIS!."
