No more carrying pails of water to and from your aquarium! The Lee's Ultimate Gravel Vac is a complete clean, drain and fill kit that connects directly to your sink faucet. It allows you to automatically begin siphoning by simply turning on your sink faucet once connected. Next, begin cleaning by inserting the Fish-Saver Cleaning Claw into the aquarium gravel and moving it from side to side or front to rear. In addition, you have complete control of the water flow during cleaning and refilling of your aquarium. By adjusting the water flow during cleaning, you are able to insure that the maximum amount of dirt is removed with the minimum amount of water.
