Reef Angel Forum

That's correct, no electrical part whatsoever.

That's with absolutely nothing plugged in! I don't have float valves installed yet.

Does anyone have any other suggestions? With nothing plugged in, the problem persists. What could be causing it?

Thank you,

Rodric

With absolutely everything unplugged it continues though. Have you ever encountered that?

With everything but the reef angel unplugged I'm getting the same: doesn't work in tank. Works in cup.

Good call Roberto! I just did it and the PH is 7.68 and stabilizing. It didn't even dawn on me to try when I saw the calibration number show up as a 0.

Do you suspect its stray voltage? I am going to try unplugging everything then plugging them in one at time.

Unplugged cloud wifi
Ph 7.0 445 <OK>
Ph 10.0 757 <OK>
Ph reads 10.0
Rinse in Distilled Water
Put in tank, waited…now reading 2.69!
Went back to calibrate - reads 0

I didn't notice this in the forum, forgive me if its already discussed somewhere. I calibrate the probe and get normal numbers. Ph 7.0 531 Ph 10.0 839 After calibration, the probe does read very close to 10.0 in the 10.0 solution. Then I reboot. PH shows super low and the calibration numbers go to 0...
