I've been having periodic spikes in my PH readings. My PH normally stays in the range of 8.1 to 8.4. Every so often, usually at night my PH will spike between 8.4 to 8.6. It usually only lasts about 1/2 hour then returns to the normal range. Recently (of course while I was away for the weekend) I had a 6 hr. spike at 8.6. The odd part about the spikes is they seem to jump up and return very quickly. The 6 hr. spike returned to a normal reading within 10 min. when I review the PH graph. This makes me think its an electrical interference issue, and not an actual PH issue.

Anybody have similar issue or thoughts on what is happening and how to correct it?

I dose 2 part. But the spikes to not seem to coincide with the dosing. I dose each part twice a day for 19 minutes using BRS dosers.
