I have a 30000 gallon above ground pool didnt open it last year opened it memorial day of this year after much cleaning and sweeping and refilling etc I was finally able to get a good shock 2 days ago (fc-10, cc-0) I have added 12 pounds of dry cya in the last week using the sock method in front of jet I am ising a new test strip kit to measure all pertinent info but the cya will not ever register. According the the tfp app I have added enough cya to bring the level up above 30. Any ideas as to why this is not reading?
