Copper Sulfate Pentahydrarte 99% Crystals 50 lb bag

This is a great product and the seller has done a great job with delivery. *******. Packaging was great and clean, ideal color as normal and ease to use. Worth the money. Thank you very much.

I used Cutrine in both granular and liquid forms, even combining it with surfactants for about 2 years but never won the battle, just barely kept the Chara from overwhelming my pond. Switched back to good ol’ copper and the Chara has backed off, rightfully in fear for its life!

Does the Job intended.

If product works properly I'll the first one to give credit to a good product!!I purchased 10 pounds first and I noticed how good this product is, we have rental properties some of these properties with septic tanks with root problems, this product fixed our problems, so I purchased 50 pounds more for maintenance to our rental properties, this product will save you a lot of money and plumbing headaches.October 25 2020The last time I purchased this product it was great!Hoping for the same quality this time.We used this product for septic tank and cesspool treatment to prevent root damages, we also used this product to clear swimming pool water (Warning small amounts according the the size of the pool, off season will save some money keeping it blue without algae)Great product!

There were no problems with the packaging. Order fulfilled as ordered.

In swimming pools fast

I have used copper sulfate in the past and it’s a great product. Really does take care of the unwanted growth in your water ways. Highly recommend.

Good stuff , Pond is clearing up a bit . Wish I knew how often to reapply thou . Use with aeration a must or you'll have a big mess of rotting vegetation that creates an un suitable water condition for ducks, fish and aquatic creatures . Overall very happy w/ product .SKI , out.
