Hi,
I trying to help someone with an aquarium Experiment. Anyways I'm trying to find sources on how to calculate how fast CO2 should diffuse through their still water surface in response to CO2 demand due to their plants. I have the aquarium dimensions, plant biomass produced over the time period in question but I'm having trouble tracking down appropriate physics info to work it out.
I'm expecting the plants to have been drawing down the CO2 to very low levels such that I think it was being used about as fast as it could enter the system. Any recomendations on formula or good sources to find the appropriate physics solution to calculate how fast/slow the CO2 would entering the system across a stagnant air/water boundary and then diffuse through the water to the plants about 15 cm away?
Thanks for any advice,
Cheers,
Johan
