Copper Sulfate Crystals

Primarily referred to as 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 this inorganic substance are crystal clear!

This is 99% pure and is packaged in its original packaging.  This is not basic copper chloride!  We only have EPA labeled product so it is legal to use as an algaecide and root control in your septic system.  In high amounts, it is toxic to aquatic life.  We want to be sure everyone has the right information to be sure they are applying correctly without harming aquatic life and any varieties of fish.  People love using it, forming a good defense against algae. For all your application needs and information regarding how to use it, please refer to our how to use copper sulfate page for more information.


We charge no shipping and intend to keep it that way!
