I was looking through my notebook and I need to amend some above statements... dKh from the effluent over 20 is good. I said 25 before, and while this is fine, it might be hard to get there. Between 20 and 30 is a good target.
I got my first CaRx in 1992 when I was 16 and all that we had back then was a notebook, which I still have... my apologies for misremembering.
Corey - tuning to optimum dKh and then raising or lowering that ratio is how you tune all reactors. Drips and bubbles can be variable between brands, but the approach is the same. I do not know if the GEO will trap excess co2, but if you have a good dKh, then you will not have extra.
