I'm getting ready to close pool next week sometime and for as much bleach (which is ALOT) my numbers don't seem to match.
Tuesday 6:50pm FC 9.5 CC 0 added 121oz. bleach
Wednesday 12:30pm FC 9 CC 0 added 121 oz. bleach
4:15pm FC 10.5 CC 0 added 121 oz. bleach
5:35pm FC 18 CC 0
Thursday FC 8 CC 0 overnight test tonight
Friday 6:00am FC 8 CC 0 added 121 oz. bleach (when I did overnight test I don't think it passed but the number I wrote says it did.....I mustve been sleepy!
9:00am FC 14 CC 0.5
10:30am FC 12.5 CC 0.5 added 121 oz. bleach
2:00pm FC 13 CC 0.5 added 121 oz. bleach
3:50pm FC 15 CC 0.5
FYI the CYA is between 20-30
Could anyone tell me whats going on?
