I'm almost there.... the water has cleared about 75%! I just did a water reading and questions:

FC = 5+
TC = 8-10 range
TA = almost turning red

PH = 8.2++ PH has spiked and it even turned blue in the vial after a minute. Should I let it alone or work it back?

Also, the Polyquat for maintenance on my pool (15150 gal) is 6oz 1x per week. At $21 per quart do you think I can go with 4oz the 2x per week you mentioned? Thinking this because my FC/TC is still high.

Thank you again, and again, and again
