Are they all freshly calibrated? And were they calibrated at the same temperature?

My Tank Thread
Fluid singlular? What pH values were the standards, and did both read them correctly after calibration?

I would treat the Seneye reading with a bit of caution. There have been several threads on the forum where a Seneye gave a false high reading up to a week before the slide needed to be replaced. In one case, the aquarist dosed vinegar needlessly and caused a huge bacterial bloom in their tank, only to find that after replacing the slide, the pH is exactly what they expected.
That doesn't explain the other two readings. Just worth mentioning.

I calibrated them with 7 & 10 Milwaukee fluid packs and dialed them both in perfectly. I just opened up another package of 10 pH fluid and checked both probes and they both read correctly. Im out of the 7 standard but I I don't understand why they would read a 10 standard exactly the same and then be so different reading the water in my sump

I've had the pinpoint monitor for years I just got a new probe for it a few months ago. The Milwaukee controller I just got to use with my calcium reactor. In the past I haven't really paid too much attention to pH unless I'm switching salts, dosing, or setting up a new tank. I wanted to set the controller to close my solenoid if the pH gets down to 6.6 and open at 6.8.
