Copper Sulfate Crystals

Primarily referred to as copper crystals, cupric sulfate, bluestone, blue vitriol, and copper sulfate pentahydrate.  These blue crystals are used as a fungicide or bordeaux mixture in gardens and food production greenhouse operations.  We also see this product being used as an algae treatment for people with ponds or lakes. Can also be used to help clear tree roots from your septic lines when you dissolve the crystal in hot water. When the water temperature rises in the summer, water bodies treated with copper sulfate are crystal clear!
