Well here I am with yet another question.
My ph is up to at least 8.2 over a period of a week. I was away for a bit and had someone adding a little bleach each night for me, so I'm not sure when exactly it happened. pH was 7.4 when I left.
My alkalinity has dropped from 100 to 80 but over a more gradual period of time. My FC is at 5.
I've added some pH decreaser (something left over) tonight and I'll check it again in the morning but because I can't tell exactly what's in this product I'm not sure how much of a drop I should expect...trial and error 'til I move on to the muriatic acid. I guess I'm more interested in learning why this would happen.
Can anyone help me with this please?
