Thanks everyone. When the FC dips below 10, I'll see where the pH is at that point. We got some Borax at the store today and we're prepared in case the pH is still low (and got baking soda as well just to have on hand for alkalinity issues if we ever come across them). Got lots of liquid chlorine and are ditching the chlorine tablets (and leaving them only for vacation use).
