Hi everyone

FC 3.14 TC 4.45 ph 7.4 ta 120 ch 135 cya 37 iron 0 copper 0.2 phosphate 153 salt 3081
20,000 gal in ground vinyl liner with swg
They gave me 2 lbs chlor brite to raise chlorine levels wait 24 hrs to add black algae killer. I tested chlorine 4 hrs later and it showed 0 on strips and Taylor kit
Is this normal
