I have been updating my drawings, etc. For the record, this is the current design of the CO2 system. Putting the in-line diffusors ahead of the temp control stages enhances bubble dwell time. Heater modules are LifeGard AF-92.

CO2BACKUP prevents runaway pH increases when the CO2PRIMARY depletes, and the Apex pH data-log reports this condition to the hour. The elapsed time counter gives up to 999 hours 59 minutes 'ON', so it is possible to calculate the yield of the CO2PRIMARY cylinder. No two 20 lb cylinders have identical yields, but I get well over a month out of a cylinder under current pH programming. I have not recently done a more exact re-calculation. The next time I change out the CO2PRIMARY cylinder I will start making notes again.

The end-of-line (EOL) solenoid is a safety, in event of either delivery solenoid sticking open, and also provides a single manual master 'OFF' on the Apex dashboard.
