Pool Chem, whadda I know???

CC means Combined Chloramines sometimes called Combined Chlorine. Total Chlorine is Free Chlorine plus CC.

Bekka,

Nope. TC is total chlorine. FC is Free Chlorine. CC is Combined Chloramines.

CC's are a very ineffective form of Chlorine...doing little good.

If you have an OTO test kit, your results are TC...the total of FC and CC's

If you have an FAS-DPD test kit, you test for FC and it gives you the ability to test for CC's as well.

Hard and Fast rule: FC + CC = TC

(When you "shock" a pool (also called breakpoint) it burns off the CC's leaving you with only FC...a very good thing. )

Ok, I followed your instructions to up the chlorine until it stabilizes and upped the alkalinity with sodium bicarbonate. It took two nights to stabilize with bleach at shock level and voila woke up this morning to "crystal clear water". Yeaaaaaaaaaaaaaaaaaaa, you guys are great. At the same time, advice from another area that my pump would loose water when I shocked it, I found indeed a plug of leaves and small pine cone in my vacuum hose. I have a beautifully clear and very clean pool now.
Huggs, Bekka
