CO2 and temp?

Hi all. I was wondering if there is an ideal water temp when injecting CO2? I know that higher temps increases the oxygen uptake rate. Is there a similar effect with CO2 and temp? I haven't really been able to find much info on this topic.

From a strictly physics opinion, I would say warmer = better diffusion of CO2 into the tank.

It's CO2. See-Oh-Two. Not C02 (see-zero-two).

I am not sure what you mean by this - oxygen uptake by cells?

Regarding your question about water temperature and CO2 injection, I would not worry too much about it. After all, keeping tropical fish/plants, there is only a narrow range of temperatures at which you can work with anyway.

No. As temperature increases, the amount of gas that is able to dissolve into a liquid decreases.

Yes. Meaning the living organisms in the tank use up oxygen at a faster rate. That not being the only factor for O2 levels, of course.

Thanks for answering my question. I wasn't too worried about it, I was just curious.
