I'm looking to build a sensor for an algae project which reads out the dissolved CO2 content of the algae tanks. This is not easy because the water is opaque and mucky, it's dissolved, not gaseous CO2, and since the pH is not constant in algae tanks, one cannot use a pH calculation. I've been thinki…

Hi,
I am interested exactly in the same topic: measuring dissolved CO2 in an algae tank.
How did you solve this at the end?
thanks
