-- I just bought Clorox 8.25% concentrated bleach, product info. says it also has sodium chloride, sodium carbonate, sodium chlorate, and sodium hydroxide, all presumably in small quantities. The modest amount of chemistry I learned tells me that these other ingredients are OK, but I would like an expert here to confirm. So: are these OK, or should I look for something with only sodium hypochlorite?
-- Also, I read in several places here that it is OK to add bleach and muriatic acid in front of the water release jets, but I just want to confirm that this OK to do for a vinyl-lined pool specifically.
