My current level is at or below 30. Should just throw a couple tabs in? FC was at 2.5 yesterday and I added a whole
gal of liquid chlorinator and FC is only 2.8 this morning. Temp here was in the mid 40s last night.
All numbers are near perfect. The strange thing is when I took the cover off PH was perfect.Nobody has been in the pool yet this year,still to cool for swimmimg.
PH 7.8
TA 120
FC 4.0
CYA 30
I have had pools for around 18 years and never had this problem until the last few years. I treat and get it perfect only to have it trend high in about a week.Any suggestions?
The only issue he has ever had is when his chorinator became clogged.

I will double check to make sure he never partially drains his pool.
