I was over at a friends house last night. She is working on some small issues with her pool. Mainly high CYA (tick over 100 using the tf100 kit) so subject came up as her FC was .5. She had bought Burnout 35 to add. I don't think they are sold yet on bleach. So she added the burnout and I waited about three hours to recheck FC. FC got a bump to 1.5 and CC bumped to 3.0. CC was .5 to start with. I do not use anything but liquid chlorine in my pool. Never have had CC issues. Im trying to understand why we had no real rise adding two bags of lithium hypochlorite??? Like is said I don't and will not use any of this stuff. Seems there should have been a much better change in FC! Any input?
