I'm new to the site and a new pool owner. Before registering I saw a post about someone in this same situation, but can't find the post now. I have a new 8,000 gallon pool and wanted the dogs to swim so wanted to be safer for them. The more I read on Pristine blue the more I don't want to use it, but I already have. I just put all the start up chemicals in 2 days ago. How can I switch back? Can I get rid of the copper or will it dissipate over time? The person who posted in the same situation said the pool store guy gave him the necessary stuff to go back and get rid of the pristine blue? I'm wondering what that was. I don't want to ruin/stain our new pool and I can't drain the water..we just paid a few hundred dollars for new pool water. Will the copper in the water hurt the dogs if they drink it? I want to get back to regular chlorine. Please help!
