Aging RO water?

Cheers, just was reading that the RO/DI is like a sponge and absorba atmospheric Co2 depends how much Co2 is in the air.

No, that's nonsense. Neither R/O nor R/I acts like a sponge. It's just water with lower dissolved solids.

Yup! The only thing that dissipates co2 is heat and time. You can't trap it, absorb it or remove it. Only agitation and warmth speeds the process...
