There is no way this pool is 14K gallons. I can do basic math! Even if it was a rectangle, 28.5' x 13' x 4.2'(avg depth, 64"deep end, 36"shallow end) that would be 11640 gallons. It's not a rectangle. It's a freeform shape with seats and steps. My calculation put the surface area, not counting seats and steps, at about 248 sq ft. 248 x 4.2 = 1042 cu ft. 1042 x 7.48 = 7794 gallons. Even rounding up for seats and steps, 8000 gallons.

Using the PoolMath app to calculate chems, the capacity that works in the calculations seems to be in the 7000 - 8000 range.

What the heck is going on!?
