The ANS Brass Air Divider L 10-way manifold splits air flow into 10 outlets, so you can install multiple air stones and aeration devices with a single source of air input. 

Each outlet has its own shut-off valves and barbed hose connection, which gives you the flexibility to control air flow into each of your air stones and aeration devices.
