I cannot seem to keep chlorine in the pool.Please review the last 48 hours below . I live in philly its been overcast / sunny for the last 2 days and hot.
Total dissolved solids 1300
so the recommendation was to shock the pool. i used 2 gallons of Sodium Hypochlorite Liquid
Tuesday 7am -- did a quick FAC test -- no chlorine --so added 10lb of Leslie Chlor Brite granules to different areas of the pool .
Tuesday 7pm pm did a full test results below
