Ok I finally got my Calcium Reactor set up and running (the baking soda did not work). It was quite a mission to find a CO2 gas bottle. It is running at one bubble CO2 per second, and about 2-4 drops of output water per second. Will closely monitor water parameters.
I made a huge mistake initially since I never rinsed the media before use - so I flooded my tank with a cloudy powder. Through experience is the way I’ll learn it seems... Grrr...
