Pond Boss Forums AERATION Should I aerate? Aeration

Windmill aerators are usually not strong enough to rapidly mix or destratify a medium to large pond. BUT, I would not bet my fish populations on the windmill not being able to cause a fish kill. Malibau Water Resources says it can happen.

With the w.mill you have little control on how much or long it will mix and destratify unless you install in the airline a tee with diversion or relief valve.

If you value your fish, ALL AERATION SYSTEMS SHOULD BE STARTED SLOWLY IN THE BEGINNING WHEN THE POND IS STRATIFIED. Better safe than sorry!
