Hi. I had to close my pool early last fall and it was a bit green when I opened. I did a slam and passed an OCLT for two nights in a row, the second OCLT passed this morning. The water is sparkling. I decided to let my FC drift down. Here are my current numbers:
FC 14
CC. 0
PH ? Was 7.2 before slam
TA 130 (will work on this later)
CH 170 (need to raise for my heater later)
CYA just under 40
This morning the FC was 18 with 0 loss overnight. I lost 4ppm during the day today. I plan on testing FC/CC again after dark.
I am wondering if FC can fall that fast or if I have an issue. Any advice?
