The Pondmaster 04511 Oxy-Flo Pond Aeration Kit raises the oxygen level in a pond or water garden. The increase in oxygen improves water quality and clarity. In cold weather, the system helps keep an opening in ice on the water surface.

As this aeration system improves pond water conditions, it helps koi, other fish, aquatic plants and good bacteria thrive. The additional circulation of water leads to more uniform temperatures in the pond. The improved aerobic conditions in the pond promote fish health and help protect fish during freezing temperatures. 

This aerator unit is made for a pond with a maximum water depth of 7 ft. The AP-20 air pump stays on shore, tubing and air stones are placed in the water. The pump has an air volume of 1700 cu. in./min. and a grounded power cord that is 6 ft. long. The kit has a 1 year warranty.
