Hi,
I reactivated my kalk stirrer since I started a calcium reactor. I am experiencing the same thing as previously with slow decrease in potency of the kalk over time. I don't want to be tied to weekly top offs of kalk powder to make the setup vacation compatible. I assume CO2 from the ATO water and CO2 entering the outlet of the stirrer are converting some of the kalk in the reactor to calcium carbonate. My fish room is held at 500 ppm max CO2 by a energy recovery ventilator (ERV). So I was thinking of having the outlet of the kalk stirrer placed under the water instead of dripping into the sump and also possibly sparging the ATO RODI water with air pumped from the room through a CO2 scrubber. Do you guys know any other tricks? I already use the Apex to control addition when the sump float sensor and pH is low to optimize pH raising effect when it is really needed.
