Pond Aeration Systems
This Pentair Aquatic Eco-Systems aeraton system is the best way to aerate a pond! It is the most economical, energy-efficient way to circulate, destratify and aerate because so much water is moved by so little energy. And there is no noise or electricity in the water. You can read about the method in Tech Talk 101.
These aeration systems use all-weather linear compressors that deliver air via easy-to-install self-weighted tubing to the diffuser assembly. Systems are complete with the appropriate couplings, valves (on larger system), self-weighted tubing (dark blue for low visibility) and diffuser(s). Just drop the tubing and diffuser in the water and plug into a 115V power source.
The small system will provide oxygen for up to 100 lbs of fish (when diffuser is at a 48" water depth; less fish weight at a shallower depth) and circulate water in ponds of up to 8,000 gallons while using only 50 watts! The compressors and air diffusers have two-year warranties. See Index for poly tubing (use part no. P200) in order to pipe air up to 1,000' from the compressor in place of running electricity to the pond.
