We have at least one significant difference in my arid area.

Rain is a chancy thing and, irrespective of drought, pond levels and water volume can vary by season. We rarely get summer rains and average(?) 88 inches of annual evaporation. Very little summer humidity. Theoretically, we receive about 30 inches of annual rainfall. Thus, a full pond going into summer can drop drastically by the time cool temps arrive.

This effects stocking densities and chemical manipulation. Increase of the natural carrying capacity through fertilization is an almost sure thing recipe for a DO crash. It really doesn't matter whether we have calm, cloudy days. We are mostly weather constrained.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
