Thank you. My tank came with a Ca reactor so I have continued to use it. Ca and dKh seem OK but the pH runs 7.8-8 which I had thought was detrimentally low. Thus I ran it only 12 hours hoping to stop the drop to 7.8 (that didn't happen). I run my effluent into a "cup" which overflows into the sump. The cup has a pH probe that is always on and runs 6.5-6.7. I had the effulent rate constant at about 60 drops /min (double the CO2 bubble count). If the tank pH is not an issue then I should be comfortable with how things are working and just use Ca and baking soda to adjust Ca and dKh as required.
Thank you for the explaination and numbers
