We have had calls about using Clorox Xtra Blue Shock with algae killing crystals.  Please note that this product is using copper as the “algae killing crystals”.  Copper is a great killer of algae, but also creates problems like pool water turning colors and  swimming pool staining.

  

Always read the label to see what chemicals you are adding to your pool water.

If you do use this product, then you will definitely need to use a CuLator PowerPak 1.0 to eliminate the extra metals.
