Uh, oh. I see the words copper in that ingredient list. You don't want to put copper in your pool unless you like things stained or like blonde hair turning green! Most people think it is chlorine that causes that, but rather it is copper. Don't use any more of that product.

You might want to verify that your filter is working properly. Find a small bag of DE and add a small amount to the skimmer and watch the returns. If you see white powder shooting back out, that means that your filter is not working. If you don't see that, then the DE may actually help your filter to work better.
