pH with Ambient co2 Readings

[trmiv]

Keep in mind I’m dosing sodium hydroxide as my alk supplement as well. Alk is around 8 dkh. We have a fresh air intake on our hvac that I turned off during the bad heatwave we had last week. Co2 got up to almost 1500 ppm in the area where the tank is. I hooked it back up a few days ago. Pretty obvious when I hooked it back up. CO2 is in blue.

Photosynthtic boost to pH in new tanks is pretty sparse at first. This can be from things that you don't even think about like film algae and bacteria, etc.

Comparing my real-life readings to the ones from the co2sys Python module, there was about a .22 bump. This is not super reliable with less than ten data points, but I did check a few other posts and it was close to within about 10-15%, or so. I doubt that there is a way to track photosynthesis enough to determine a bump in a tank by tank basis.
