Air Flow Control Lever Valve4-Way with Airline Tubing Connector for Aquarium, Fish Tank

Well made, valves tight. Solid unit, very happy

It works. You plug it in, attach your stones and they bubble. Valves do as they say and shut off air flow, spectacular!

Awsome and arrived right on time

Very good

I thought this would be great to set up with my 3 tanks. Too hard to figure out what kind of setup to use with this, what kind of tubing it requires, or even what kind of pump is required for it to work. Returned it and bough something else. Not worth my time.

Good deal

Helps balance air to different aquarium features

Put this Air Splitter right to work, using it to combine the output of two small air pumps. Now I have a rolling boil in my compost tea brew. Should help keep things from going anaerobic. Being stainless steel I can submerge it to the bottom of the tank, and not be concerned about it floating up or corroding.
