From Swamp Green to light green and cloudy

Post a picture of the pool and show me the gallons configure in the app.
What brand/name liquid chlorine are you using?
Confirm by counting the bottles how much you added?
 
What size sample did you use for the FAS-DPD test? I'm guessing it was 25ml and you counted each drop as .2FC.

Next time test with 10mL sample size and each drop is .5FC.
