I need to control pH and oxygen levels for acidification and hypoxia purpose. It will be carried out in seawater. Anyone has experience on this kind of stuff?
Thanks in advance.
Hi, you can use CO2 gas or carbonate for pH and N2 for hypoxia. Check out the new guideline on conducting and reporting ocean acidification experiments. http://www.epoca-project.eu/index.php/guide-to-best-practices-for-ocean-acidification-research-and-data-reporting.html
Hi, I also agree with Le to use CO2 gar or carbonate to reduce the pH. As sea water is usually alkaline, you can use lime to reduce the pH. It would be nice if you please confirm what you want, reduce or increase or keep it as it is.

Hi,
for an example of how this has been done previously please see this recent work by Bockmon et al. for an aquarium system. A

A similar system could also be used for other biological or biogeochemical studies. The important aspects are the active controls of pH and pCO2.
On a larger mesocosm scale the work of Riebsell et al. may be of interest.

I hope this helps.
