Have you checked your O2 levels during the 3-4 am lows? I understand that in MN your water temps will not be as high as Texas, so your O2 demand and saturations will be different.
One thing to caution anyone down south using your system is that it does not work at night, and that is when we need it most. Further, during the still, hot, and cloudy days of summer, your production will be limited.
With that said, nicely done!
