My pond is a little over 3/8 of an acre, the system I purchased below is rated for up too a 1/2 acre pond, should have been large enough for mine.
The ForeverGreen Economy Aeration System 1 comes with 1 Vertex CoActive Airstation
This system includes a Thomas single piston pump, 1/7 HP 115 v, 1 phase Wob-L piston type built for continuous use and equipped with a thermal overload protection. Heater hose, air filter and a liquid filled pressure guage are included.This system is ideal for small ponds up to � acre requiring up to two turns per day based on an average depth of 12 ft. This unit draws 285 watts (3.6 amps) and produces 1.22 cfm.Pump can be placed up to 2000 ft from pondside. Pressure is rated to 50 psi, (average pond depth of 12 ft will require only 6 psi) Weighted tubing sold separately
I was told that this system would turn the pond over about twice a day. The results from the biologist are 1.75ppm DO reading. He said they should be around 7ppm and that anything less than 3 is a sure fish kill. Water temp at the diffusers were the same top and bottom. His suggestion was my system is not large enough and I should imeditley get a pump and start pumping water from the pond into the air to quickly get the DO level back were it should be, and than purchase or add on the my present system. Bottom line was I will loose all fish if one or the other is not done quickly. All catfish are still staying on surface for oxygen, and the talpia are now dying. So off to Lowes I guess to get a pump after work.
