Ok, that is good on the sock and filfer. How many ppm did you add?
2-4 ppm daily FC usage is normal with a decent CYA level. It will be more with low or no CYA. I wouldn't push the slam button just yet. Add another 30ppm of CYA in a sock and keep FC 3 or higher at all times. Test CYA 24-36 hours after it is dissolved from the sock.
You can do a true Overnight Chlorine Loss Test any time you want. The 1 to 1-1/2 doesn't look like an after dark and before sunrise test.
I think you are probably ok. Any signs of algae? Cloudy? Slimy? Greenish tint?
