At 12:20 AM I am still up so I decided to test again. The last time I tested an hour after I poured bleach in a jug raised my FC 2.5 PPM. My FC was at 5.5, and I added 4 jugs, assuming I would be around 15.5. However, I was only at 13.5, so I am pouring a jug through my skimmer to get around 15.5-16 PPM. The other test I did was with generic bleach when I got a rise of 2.5 PPM, and now I am using Clorox. They are both 6%.
