CC= combined chlorine - it is chlorine that has been "spent" but not burned up in the process of killing organics. You will ususally have it when your pool has been heavily infected with organics (algae, tanning lotion, urine, etc.)

When you shock the pool - it not only kills the bad stuff, but it also "burns up" the combined chlorine (CC).

CC are tested with the FAS-DPD chlorine test kit I told you about a couple of days ago.

You mentioned your test is dark brown - are you diluting with distilled water and testing - 4 parts distilled water and one part pool water? If so - then your chlorine level is too high - you should get a vibrant yellow - but not dark brown.

You should go to http://www.poolsolutions.com and read the articles and check out the "sticky" threads at the top of the forums - they will help you understand this process a lot better and the terminology.
