Use the compare tab in the CaRx pH grap and overlay the temp on the pH graph. Temp has a direct impact on pH so if your temp is going up and down by even 1 degree, your pH will follow.
If your flow rate is consistent (which it should be with a masterflex) then your Co2 rate is fluctuating (low Co2 pressure in the tank could cause that) or the rise and fall coincides with temp or something else. Could even be something electrical in the tank that is turning on and off. Probe wires should never be run parallel to power wires for example.
