Dear monocus, that's great that you confirmed how to make CO2! I have two stones to use, but thanks for offering.
I have another question (there may be a few more).
We got the experiment underway, but, I realize that I'm not sure whether I have to do anything to the nanocloropus before adding CO2, i.e., siphoning off, adding of sea water, etc. Once there is evidence of phyto growth (how long will that be?), should I start a new bottle with salt water in it, and add only some of the phyto, or should I just start adding CO2 to the already growing culture? Please advise. Thanks.
