Pond Boss Forums AERATION Systems questions Diffuser Locations and Turnovers per Day???

I have the vertex XL5 in my .25 acre pond. My pond is 1.49 acre feet or 485,518 gallons. If I did the math correctly I�m getting 1.22 turnovers per hour! My diffuser sits 1 foot off the bottom in the center. When I purchased my diffuser I sought help from vertex and an old member here (Ted from Forever Green). I was told you can�t have too much aeration and hearing that you can is news to me. I have never had any kind of fish kill and my system was run continuously during the summer only for 7 years and at night on a timer for the last two years. I think my pond was cleaner running it continuously.

ETA: Actually I�m getting more turnover than what I stated because I used your chart that gives gpm for 10� or 12�, I used 10� when my diffuser is actually at 11�.
