I added another gallon of bleach after testing, will test again to see how high CL went up. My fill water is city water, it's on an automatic fill system. Right now the pool doesn't look as green as before, now just really cloudy. I've got a skimmer sock and I'm cleaning it twice a day as it's turning pretty green throughout the day, also have some scum balls that I'm having to clean daily as well. I also brushed the walls today as well.

As far as the prior chlorine I was using its Leslie's 3" Jumbo tabs. The label only says "Sodium dichloro-s-triazinetrione dihydrate 99%, Other ingredients 1%" So i'm not sure what the "Other ingredients" are. The trichlor was Leslie's Chlor-Brite and the label says "Trichloro-s-triazinetrione 99%, Other ingredients 1%". I discontinued use of both of those when I switched to bleach.
