Hi Everyone,
OK, I realize that my question is not easy to answer and I'm not looking for a definitive reply. But, does anyone have any idea how much CO2 fish produce - either by excretion from the gills, urine or faeces? Indeed, which of these three would account for most of the CO2 produced by fish? I am assuming it would be mostly from the gills but I would welcome any replies. Is the amount of CO2 from the fish a significant source for live plants?
