Hi,
I have a low maintenance planted tank with a spray bar that agitates the water surface for better gas exchange. I also have a Seneye that records the pH of the water. I have noticed that at night the pH rises and during the day it falls. One would think that during the day where plants photosynthesize, use up CO2 and thus the pH would rise and during the night where plants release CO2 the pH would fall. The opposite happens though and I cannot explain it.
Any ideas?
