Pond Force™ Koi Pond Air Pump Kits Submersible Available in two sizes andPond Force Koi Pond Air Pump Kits give you everything you need for pond aeration, from the air pump and cabinet to the airline tubing and airstones. Aeration is needed for proper oxygenation during the summer months, when higher levels of fish activity require higher levels of oxygen, especially because algae can rob the environment of oxygen. In the winter, aeration is necessary to leave a hole in the ice for gas exchange and oxygen transfer.
