Default Some CO2 Relevant Data
Yesterday I found some time, had my pH probe freshly calibrated, and did a couple of experiments. I took a tank sample of water, let it sit on the counter for several hours, measuring pH periodically, to see how long it takes for the pH to stabilize. And, I mixed up a bit of sodium bicarbonate in distilled water to get some KH, let the water sit on the counter and measured pH periodically to see at what ppm of CO2 it would settle at. The data is plotted on a couple of graphs on the attached jpg. I'm really puzzled about what it all means. Any ideas?
