If highly aerated, the CO2 dissolved in the water will acidify the water for a period of time. As the gasses dissipate the PH goes up.

I should’ve been clearer. Ultimately, standing water in an open container at room temperature will acidify as it equilibrates with the atmosphere. Without intervention, distilled water will decrease in pH from 7 to 5.5-6 in an open container at room temperature.

It’s possible for mechanical aeration to temporarily increase the dissolved carbonates to a point where they interact with other dissolved elements in the well/tap water and spike alkalinity. We don’t know enough about the air quality in this case. There are a lot of variable at play here. There could be microbes feeding off of the dissolved organic carbon. It’s a mystery.

If my explanation sounds vague or contradictory it’s because we’re describing molecular processes in general terms and there are too many unknowns.

Just tested run off they range from 5.8 to 610 do u think there ok
