disappearing free chlorine

[woman.n.a.shoe]

My free chlorine is almost at 0 but I have very high total chlorine. I am afraid to add anymore bleach. Can anyone tell me why, how to fix it, and if the kids can go swimming.

Thanks,
Alicia

Posting a full set of test results would be the first step but to get rid of combined chlorine (which is what you have if the TC is high and the FC is low) you need to add MORE chlorine to the water to break the chlorine/ammonia bond in the CC!
