Can you explain what you mean by:
We also have a GEO calcium reactor we picked up used, but have yet to actually set it up. I need to research more. I feel like there is still so much I don't know, but your thread helps a lot. I just don't quite understand what the different settings are. I assume the bubbles/min is the rate that it drips out? The PSI has something to do with the amount of CO2 pumped in?
