Python Squeeze Bulb

This squeeze bulb from Python is designed to get a siphon flowing with just a few simple squeezes. No more having to suck on the end of the hose and accidentally getting a mouthful of tank water. Just place your hose or gravel vacuum into the aquarium, squeeze the bulb on the other end and water will begin flowing through your hose and out of your tank. It also comes with a ¼-inch and ½-inch adapter to fit your size hose.
