I wrote down some pH values in my tank with the corresponding co2 readings in my home as I turned the AC on over the last few days.
I was hoping that others could post and we could start to understand the drop in pH as co2 goes up.
I measured with a $50 amazon co2 meter and a $20 Amazon pH pen that I just calibrated - these are not super accurate tools. Took all readings at 21:30, so near the end of my light cycle where the pH should be the most high - I did not take low readings.
421 co2, 8.41 pH
512 co2, 8.39 pH
665 co2, 8.24 pH
719 co2, 8.17 pH
Anybody else have any numbers as pH and co2 moves up or down?
