Anyone else having low PH compared to last summer? Looking at my logs I was between 8.1 & 8.3 during the summer last year. This year I am around 7.8-8.0. It usually dips in the winter time and gets higher during the summer (open windows and such). Wondering if its just me or maybe the air quality is truly effecting the tank. From the fires maybe? I use kalkwasser to maintain alk/ca/ph but it just cant keep my PH up this summer...
