i use a five gallon bucket and one gallon pitcher. i use the pitcher to empty the tank after i've vacced it and then use the bathtub to fill the bucket back up to refill the tank. pain in the butt! sometimes, for my ten, i'll just use the pitcher and the bathroom sink. when i get bigger and better tanks, i'll prolly invest in a python, which is what i used when i worked at petsmart.
