Here's where this stuff gets frustrating for me. Last night evidence supported the idea that my Kalk Stirrer motor was producing interference that was evident in the pH graph. Quite definitively I thought.
So I turned that timer off to see if it made a difference. Smooth graph this morning. No regular hourly blips. Proof right?
So I turned the pump on to try reproduce the spike and it won't do it. Carries on producing the smooth-ish graph. What I would definitely consider acceptable.
Now it gets interesting. In "frustration" I turned the Stirrer motor off and suddenly the spike appears in the graph. My guess is that when turned off, a capacitor or something in the power supply is causing the spike. Bizarre, but not entirely inexplicable.
Still going to change the stirrer motor out today and see if that has any effect.
