This has been a process!
The prop tank is on a staggered schedule, and after 1.85 gallons a day of fully saturated kalkwasser, I add 10ml of esv 2 part. I add it at my lowest PH point, 6am, a one shot dose.
This usually takes high ish 8.0, and pushes to 8.1. After that, it kick starts the day, and seeing 8.2 before actinics(9am) go on the display. At 2-3pm, it's around 8.4 and stays there until 1 hour after actinic, (9pm).
I feel like I have found the ph pocket

The ato still runs,(.5 gallon day)so I could actually bump kalkwasser, but this gives me wiggle room to run this way in the winter, when windows open, fans off, a true evaporation, not artificially boosted to add more kalk.
