Place the air pump outside the aquarium away from areas where it may get splashed. Attach a length of standard airline to the outlet and run this into the aquarium. Attach the airline to a TetraTec AS air stone or to an airpowered ornament. It is important to install a TetraTec CV4 checkvalve in the airline to prevent water being drawn into the pump. Use the flowcontrol valve that comes with each APS pump to control the amount of air produced. Always read the instructions carefully before use.
