8/26 update:
Had pool water tested today:
Total Chlorine: 2.0 ppm
Free Chlorine: 2.0 ppm
pH: 7.8
Total Alkalinity 105 ppm
Calcium Hardness: 360 ppm
Stabilizer: 50 ppm
Total dissolved solids: 4200 ppm
salt: 2800 ppm
Water temp: 83 degrees

I'm actually encouraged that the chlorine was not 0 as it had been the last couple weekends when I brought samples in. I ran the pool pilot test a few times, now getting a reading of ~14-16 volts and 3.4-4.0 amps while the "check/clean cell" light was on. Ran test after "check/clean cell" light went off and got 18 volts with 6.5 amps.

Based on the water test results I added ~1/4 gallon acid, this is typical I add this weekly, and I added 2 lbs of stabilizer and a 40 lb bag of salt. Then I brushed all of the pool surfaces and added 2 gallons of liquid cholorine because I had a light shadow of algae on some of the pool walls, this brought the free chlorine up to 5ppm+ (above scale on my home test kit).
