We need to feed an aquarium with CO2, if we heat CACO3 to liberate CO2, the cold CaO could absorb CO2 from the air and be reheated to liberte more CO2?

Unfortunately it doesn't work like that. The amount of CO2 in the atmosphere is far too small to drive the reverse reaction at any appreciable rate...it would take a long, long time to regenerate the original amount of CaCO3.
Oh yeah, what lenpol said. Dagnabbit, I forgot about the moisture in the atmosphere!

NO!!!!
The CaO(Lime) will absorb moisture from the atmosphere and become Ca(OH)2 (Quicklime).
