Bill D, if his pH was 8.28 in the evening, what would it be mid-day when it is at it's highest reading in the pond?
In my pond, the PH varies very little with time of day. I suspect the high alkalinity acts as a buffer that keeps PH pretty stable but I'm not a chemist. Hopefully, some other folks with experience with this kind of water will chime in.
