I drained and refilled the entire pool a week ago.
I have been trying to balance the water all week.
Latest:
FC 8.0
CC 0
pH 7.8
TA 200
CH 250
CYA 40
I have added acid to bring down the pH over the week when I wasn't shocking with FC >10. It's 0.2 higher today than a few days ago last I checked.
I added CH and got to 250.
I added CYA and got to 40 (I even ordered the standard CYA 50 so I could compare and the pool store used the dot with the handle and I looked at that myself. I was so concerned about CYA that I needed to make sure for myself so I'm pretty confident it's 40).
Starting Friday I shocked the pool at algae levels for over 24 hours - I tested frequently and added when needed and tried to keep FC at 16-17. This morning @7:45AM I thought I passed the OCLT. So today I thought I would stop shocking and see where the FC landed and start to try to keep it at the standard min 3 & target 5 (for CYA 40).
At 10:00PM FC measured 8.0!! I thought standard loss, even for a direct sunlight pool like mine was around 3-4. Why in the world would my pool lose so much FC? Is that normal?
The water looks great - it looks better than ever since previously my CH was well over 600 and CYA was way over 100 prior to the drain/fill.
Thanks for help in advance.
