Thanks for all the replies, I am just trying to figure out what I need I suppose.
The system was off for about 6 years and I just turned it back on last year when I took ownership of the house from my mother.
The bass and bluegill seemed just fine with the aerators off all those years.
I remember a few dead fish over the years but no big fish kills.
As far as I know the aerators were installed to reduce muck and weed growth.
May have just been a good aerator salesman also.
Is 24/7 aeration the best bet?
