That is strange.

I think it can be difficult to trouble shot using charts as they don't update enough, here's something you can do that might help pin point it.

Disable the pH in reef-pi.

Open the Pi terminal window and type in the following commands.

This downloads a python script
sudo wget -c https://robo-tank.ca/Robo-Tank_pH_Script.zip

This unzips the file
sudo unzip Robo-Tank_pH_Script.zip

This runs the script
python Robo-Tank_pH_Script.py

After the last command it’ll say Enter Command: Then type in the following, must be a capital letter.

R

It should print out a pH value. Now type in the following.

POLL,5

Now it should print out the current pH every 5 seconds. Turn things on and and off and see what happens.

Make sure to disable in reef-pi, you can't read at same time from two scripts.
