dichlor and trichlor adulteration How to know

[javox]

Thank you PoolDoc. I will look for those guidelines. Can you tell me which dilutants are usually used? I mean, should i be worried of something pernicious gettting thrown in my family pool? One thing is to get inocuous extra stuff and another thing is to throw something that may harm my children's health.

Borax, magnesium sulfate, & copper sulfate are among the most common -- but the container will not usually identify them, and certainly not by those exact names.

If you simply avoid buying diluted dichlor / trichlor, you won't need to try to avoid specific ingredients.

Regardless, that's your only practical option, since it usually takes a fair amount of knowledgeable 'sleuthing' to work out what's been added . . . and even then, some guess work is involved. You can learn how to tell WHETHER a chlorine product has been diluted, but probably not WHAT it's been diluted with.
