Yes, aerators and lower feeding completely wiped out the algae. However, I got in my oxygen probe so I wanted to get an idea of the levels at the pond. See the pond pic and the readings. I was not expecting so low readings at 8’+ Note, my probe is only 10ft max. Temp yesterday over 95 and no rain in weeks.

Took another reading 3ft away from A2 @ 9ft = 1.7mg/L - 82.5F

I’m using 5.7cfm compressor with bottom diffusers. Seem’s to be kicking of plenty but I’m stunned by the drop to 0 when I get to 8’+. Should I move both diffusers to deepest sections? I’m not getting any foul smell. They’ve been running for a few weeks now 24/7. I was concerned about having most diffusion so close to the spillway. That is why I have one up in the shallow by the spring. Thoughts?
