OK to SLAM with Copper in water?

Vinyl liner pool, previous owners used a product with copper in it. EZ Pool. Pool won’t hold chlorine, CYA 100. No algae present. SLAM to see if there is anything bacteria in the water. Will this unbind the copper and cause a catastrophe of stains to take care of? Or turn the water brown?

Have you done the extended CYA test to be sure your CYA is only 100?

Best move would be to drain/exchange water to get your CYA to 50 or less and remove some copper. Then you can follow the SLAM Process.
