Kalk Reactor with CO2?

[BCOrchidGuy]

how would this work? With a kalk reactor my understanding is that you want to have a power head come on a couple times a day to mix the Kalk, then let it settle. What if there was a CO2 injector and it was on a solenoid so when the power head comes on the CO2 would come on. So basically make a Ca reactor but have Kalk in it, and don't have it running 24/7 and have it fed to the sump by a drip. Does this make any sense or am I just more confused than I was before?
