Great, you're just trading one toxin for another. Many people are already to intoxicated with copper in their bodies because copper is everywhere. I've heard a person say that there is great deficiency in copper, but that is very misleading. Many people might be deficient in their blood chemistry simply because they can't metabolize it well for one reason or another but that doesn't mean their is far, far too much copper in their tissues. When you test for heavy metals in the body, blood test are useless because more than 95% of those metals are going to be in your tissues, not in your blood. So the best way to determine this is with a chelation test. It's the same with copper because we need very little to maintain optimum health. If you have to use copper, why not balance it with zinc and made sure and equal, or better a slightly higher zinc content is the pool to compete with the copper absorption through the skin, since zinc competes with copper in the body.
Funny you mention zinc because ClearBlue is the only mineral system that uses copper and zinc (as well as silver :). Remember that these minerals are at a VERY low level to be effective in the pool against algae and microorganisms. You will get the same amount of copper from many household showers.
You guys are lying about the salt, aqueous HCl is different than aqueous Cl-, very disingenuous. Sure its elemental chlorine, but you are lying about the forms by not staying that.
There are copper ionizer systems on the market that put waaaay too much copper in the water which can lead to discoloration of hair and anything else in the water. For this to happen, the chlorine must also be too high. Note that chlorine alone can also lead to this if it is too high. In 10+ years, this has never been a problem with ClearBlue. This is because it is intelligently controlled so that the minerals never get too high.
