OK, so I want to be sure... My tf-100 tells me my CYA is about 50 (hard test to be satisfied with) but its close. My water is crystal clear... looks great. PH I keep about 7.5, and TA about 70...
To the point over night FC test shows more than 1 ppm loss... I have never needed to shock this pool (well not while I have owned it and have used BBB for upkeep), but by the over night FL loss I guess I should... So I decided to raise the FC to 20 (20-25ish) and shock... well I had it up to 24 lastnight and woke to 11... it did rain so I will not rule that out... but not sure why it dropped so much... I have brought it back up to 22 and will chk it agn in a few hours. Any thoughts or ideas? Should I be shocking (thinking so)...
thanks for any help.
