Application

• 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 air-powered ornament. 
• It is important to install a TetraTec CV4 check-valve in the airline to prevent water being drawn into the pump. 
• Use the flow-control valve that comes with each APS pump to control the amount of air produced. 
• Always read the instructions carefully before use.
