Apex ORP reading low

[MThomson]

Hey all,

move been watching my ORP steadily drop from the high 200s to 60 over the last few weeks. I’ve tested the probe by placing it in a bottle of hydrogen peroxide and it jumps up to the 300s. All livestock is accounted for and water parameters are all within range. Can anyone point me in the right direction on how to troubleshoot this issue?

Possibly get some calibration fluid and go from there.

Whenever I powercycle the entire apex system, it jumps to 300 and then drops. So I’m gunna order a replacement probe
