I would say neither
You really need to get yourself a decent FAS/DPD test kit (Taylor K2006c or TF Testkits TF100 in the states) to get accurate results as maintaining an appropiate shock level means testing quite often during the day
Chlorine / CYA Chart
Recommended Pool Levels
Your salt is only lost through leakage, splashout and backwashing
Use these common products to balance your pool
Muriatic acid (hydrochloric acid) to lower pH and TA
Bicarbonate of soda to raise TA
Aeration will raise pH only
Soda ash will raise pH and TA
