Pond Boss Forums AERATION Systems questions Greeting all, I have an aeration question

If you have ever seen the inside of an algae culture incubator, you will realize you probably cannot create enough light and bright enough to grow algae in the hypolimnion. Even nature (sun) does not have enough or create enough light intensity on a cloudy day to keep phytoplankton growing adequately to produce a surplus of DO. Fish kills can happen due to lack of DO after several cloudy day periods. Research the light intensity needed for growing algae cultures. Now extrapolate that to the volume or area of your hypolimnion.
