Lee's Ultra Gravel Vac's Self-Start Siphon feature has made aquarium maintenance a whole lot simpler. These easy-to-use vacuums are designed to separate and remove debris from the aquarium during routine water changes. The unique wide mouth nozzle increases the Gravel Vac's surface coverage by 20% for faster, more efficient cleaning that uses less water.
Using it is easy! With the Gravel Vacuum cylinder submerged in the water, simply move it up and down a few times to activate the Self-Start Siphon.
