Already been done. The answer is yes. Prior to installing my SWC, I used bleach and always had about 0.5 CC. After installing the SWC, my CC dropped to 0 and has been there ever since. Sean has also mentioned in the past that the concentration of Cl is high enough that it does act like a continual "shocking" process. I can definitely confirm the results, as I have not had to shock the pool since I installed the SWC.
