on the beast I ran 45-60 BPM with a 120 ml/min flow rate for the same pH. My reactor prior to that without recirc line was 60 BPM+ with 120 ml/min. With recirc it dropped to 60 or slightly less.
much higher than this one. this thing uses almost no CO2 to keep the pH where i want it. I counted before lights out and it was near 9-10 per min for 6.9-7.0, 80 ml/min.
