Pond Boss Forums AERATION Systems questions Fountain question

There's roughly 4,480,451 gallons of water in the pond. Typically with a bottom aeration system you want to bring a minimum of 1.2x the water volume to the surface every 24 hours to get it in contact with the air to transfer O2 to the water.

I don't think that a fountain @ 210 gpm by itself will be sufficient.
