This update is coming in a little quicker than the others have in the past:
Due to the availability of the components, the cost and how often I have to refill/mix the Fauna Balling Light system, I decided to bite the bullet and delve into calcium reactors. (Disclaimer: I'd recommend Fauna Marin's Balling Light to anyone and I did not have any issues with it while using the system)
Buy once, cry once came to mind. I ordered a Deltec TwinTech CRTT-1500 from Top Shelf Aquatics along with the other things necessary to get a CaRx running. To try and thwart the depressed pH from running a CaRx in a well-insulated home in FL, I also opted to add an AvastMarine K1 Kalkwasser stirrer.
Currently, the K1 is being fed 4mL/minute of RODI to trickle saturated kalkwasser into the system. The TwinTech is dispensing 5L of effluent/day with the recirculation pump running at 50%.
I reached a pH peak of 8.24 the day the K1 was installed. I'm targeting an alkalinity between 7 and 8 dKH, with the last KHD test reading 7.2 dKH. I still have some fine tuning ahead, but so far so good!
