I'm not an expert in any form regarding CO2.
IMO breaking up the bubbles from several larger ones to several smaller ones is just wasting electricity to run the Koralia.

I can see some points for the argument that smaller bubbles of the gasses coming from the sponge filter creates a bigger diffusion similar to using an air stone with a CO2 system but I don't think you are adding any NEW CO2 to the mix, just making smaller AIR bubbles. Yes, there is some CO2 in AIR but you will not be adding any additional CO2 by what you are doing currently.
