Hello to everyone.
I got an awkward behaviour in my setup that I’d like to discuss:
Since last week, I’m getting inconsistent ph readings (ph fluctuations from 7s to 8a within a few seconds) I tried everything in the reef-Pi side (replace RPi boards, re-install everything, re-calibrate probe, have the electronics inside a metal box) all resulting in the very same instability.
Then I moved to my tank to investigate potential interference and I found that this issue happens only when I have the AI Prime powered on. I’ve tried a different power supply for the AI with the very same result. I also tried a few different power supplies for the reef-pi which improved the reading but did not fixed the issue (using an iPhone charger reduced the variation to around 0.5 ph)
In summary, the only way to get an steady ph reading is to either have the AI removed from power or to have the reef-pi connected to a power bank.
Would you guys have any suggestions to help me fix this issue?
Thanks in advance.
Paulo
