    Testing error is always possible. The other possibility is you are doing the evening test to soon after your last dose. You swhouold give it about 30-60 minutes to circulate, then test.

    Do you have any other chlorine sources in the pool?

    Unless you add more chlorine, it can ONLY go down.
