Has your chlorine held overnight yet?

[no1ford]

Yes-for three nights!

If your FC is holding and constant then let your chlorine levels drop and then add sequesterant. If you are using a TSP based floc (most of them are) you are putting phosphates (algae food) into the water! If you want to continue to use floc after I have advised against it then there is really nothing more I can do to help you. You have also not posted any test numbers which makes it more difficult to know what is going on in your pool. You really should be reposted the most current results each time.
