Bestway Skimmer Leaking, Need Advice

Just installed Hayward Skimmer on Bestway 14x4 round above ground pool. Water filled since last week , set up Intex Crystal Clear sand filter SF70110-2. Now skimmer and retrenched valve leaking so dropping water level to redo.
August 10 readings with TF100 kit
CI = 1ppm
BR = 2ppm
PH = 8.2
FC = 0.5 ppm
CC = 1 ppm
TC = 1.5 ppm
CYA = 20

Should I add liquid clorine 10 pct or Shock?

Thank you all
