Could aeration damage my pond? - 05/04/17 05:36 PM
I have a 1 acre pond, 2.1 million gallons and 12' max depth. Here in Northern California it is full right now from all the rain this season. I have catfish, bass, and bluegill in the pond. Aquatic plants began forming during our 4 year drought when the pond was very low.
Very soon, I will begin diverting creek water to offset evaporation as temps rise. That water goes into the pond via a 3 inch pipe.
I built a venturi using 2" pvc, using the diagram posted in response to one of my other questions. I'd like to install this and forget it ... but, I don't want to over-aerate or do anything to harm my pond. I read that folks with diffusers slowly introduce aeration, starting at 15 minutes per day. But that seems to be a lot more air than what a venturi would do, plus my setup is barely below the surface, not at the bottom.
Do you think I need to gradually phase in this new venturi system, or just turn it on and leave it on?
