Contest entry/calcium reactor

Sounds difficult to control the CO2 production, IMO. I use that exact reaction to generate CO2 in a controlled manner in a product we are developing at work (nonreef), but I do not think it will be easy in a DIY project. You'd need a dosing pump for each of the acid and the baking soda, a closed chamber to retain the CO2 and push it into the reactor, etc. Uneven CO2 will lead to unstable alk.

That said, all a reactor needs is controlled CO2 addition, flowing seawater, and media.

Thank you so much. That is some useful information. My project is going to be very slow moving. I plan to experiment with the CO2 generator long before going into actual use so this gives me some added variables to consider. Perhaps a 3rd vessel to act as a storage tank at maybe 25psi regulated by a pressure release valve.

You're welcome.

FWIW, I think it would be complex, if not dangerous, to generate and store 25 PSI from a chemical reaction.

Noted. 10 then.
