So in my haste one day I bought a bucket of Clorox Xtra Blue 3" chlorinating tablets because they were on sale and I figured I could use them while on vacation.
I have put them in my inline chlorinator but just yesterday I discovered that they have some "extra ingredients", someone suggested Copper or other heavy metals. According to the MSDS sheet (link posted below), there are some "trade secret" ingredients, 3-8%. How is it possible that they aren't mandated to tell you what that is?!?!? What am I missing?
