I posted this last night but then it must have got lost in the move to the new server. I initially had a response from Watermom that was helpful. I"m using the Taylor K 2006 testkit and have a 18,000 gallon fiberglass pool. Water temp was about 71 degrees.

My readings are:
TA 120
CYA 60
PH 7.4
FC 4.0
CC 3.5
CH 160

I raised the FC level to 10 times the CC level as recommended in the Taylor test guide to get rid of the CC. Next day the CC was still 3.5. I was using 3" Chrloine Tablets from In the Swim until about a week ago but now use clorox. I followed the instructions on how to test the FC and CC using the Taylor guide. Watermom thought my CC reading might be wrong because it's so high. And she may be right since the water does not smell like chlorine. Any suggestions on dealing with the CC? Thanks for your help.

Yes, there were some bumps moving from there to here -- most of the attachments got disconnected

Anyhow, there are two likely possibilities with your CC.

=> First, you could be making a testing error. But if you are using the K2006 and ONLY the DPD drops + the DPD-FAS drops, and have pre-rinsed your tube, it's hard to make that sort of error.

=> The CC could be real. If so, get some borax, and raise your pH! If it IS real, and isn't stinky yet. Also, do NOT cover the pool -- the chloramines leave as chlorinated gases, and can damage a cover. If they are real, it will take time, sun, and quite a bit of chlorine to get rid of them. Don't work about the break-point calculations -- there are only few situations where those calculations actually apply, and most of them are NOT in pools!

To make sure I get this right. I should raise the PH level and then raise the Chrlorine levels each night, check it in the morning, raise the chlorine level if needed until the CC goes away. Should I raise it to the shock levels from the Best Guess Chart? Thanks for your help.

That's it, exactly.

But let us know if you do NOT see chlorine levels dropping overnight.

I've go it to the point where the Chlorine levels are consistent from the evening to the morning. Last night, I upped the FC level to 17 and this morning it was still holding at 17. CC is still at 3.5. Do I continue with the process and then the CC will eventually go away?

Ok, you've made progress. But it's still not clear to me what the source of the problem was. Please read through this PoolSolutions page, and see if anything jogs your memory:
