A simple way to perform quick water changes and clean gravel. Just a simple up and down motion with the intake tube will quickly prime the siphon to begin water flow. Debris is pulled away with flowing water and disposed of while gravel falls to the bottom of the aquarium. Recommended for use in 15 to 55 gallon aquariums. Includes 6 foot flexible hose, self priming intake tube, hose clip, bulb for priming.
