My ph is down to 6.8 however this pool always tends to try to stay in the high ph range. I recently lowered it. Obviously by a litttle too much, but I feel that it will come up on its own. My alkalinity was 70. My chlorine is back down to 0. My test doesn't separate FC & TC. Nor does it test for hardness. I have a fiberglass pool. 12,500 gallons.
