Copper Sulfate Pentahydrate Powder - 5 Lbs.

I use this to knock back a drain line that's had roots growing in it. This dissolves quickly in water and doesn't leave residue, color, or a stain in a toilet which is how I get this product into the drain line. I would buy this again.

It only took 24 hours for the moss become dead or dying. Copper Sulfate was great, thanksEnlarge and look closely to photo.

I use this stuff for copper plating other metals. Works good.

Use this to prevent roots from growing into mainline pipe. Had back up due to roots growing into pipe -been using copper sulfate pentahydrate x2 per year for last 5 years. No issues since. Great deal.

I recently purchased copper sulfate pentahydrate powder, and it is exactly as advertised!What I Like: The quality of the powder is excellent. It arrived in a secure package and was exactly the right consistency I needed for my projects. The vibrant blue color is a clear indication of its purity, and it dissolves well in water, making it perfect for my applications.How I Use It: I primarily use this copper sulfate for gardening and as a laboratory reagent. It’s effective for controlling algae in my pond and is also great for various chemical experiments. The instructions provided made it easy to use, and I appreciate the detailed information on the packaging.What I Don’t Like: There’s really not much to complain about. If I had to pick something, I wish the packaging was a bit more resealable to keep it fresh after opening, but it’s a minor issue.Any Problems? I haven’t had any issues at all; it’s been consistent in performance every time I use it.What Others Should Know: If you need high-quality copper sulfate pentahydrate, this product is a reliable choice.

Our semi-rural area has septic tanks and lots of trees. Tree roots LOVE septic tank pipes.In our case, the roots broke the pipe, thus causing the tank contents to back up into the shower.The guy who fixed our problem highly recommended we sprinkle a bag of copper sulfate onthe ground over the tank and pipe. He said the rain would cause the powder to sink into the ground.and would prevent the roots from growing there.So, we ordered a 5 lb. bag, and once a year sprinkle the powder in the area., and have had no moreproblems.Am happy with this company, and this product. Their price is reasonable, too. Would highly recommend.

I live in an area that is constantly under construction (new development). There is a lot of dust making my pool water dirty. I used to see green algae in the spots where is hard to reach by the sweeper. I increased chlorine but didn’t help. I started using the copper sulfate every other week and the algae is gone. I even had to lower the chlorine but kept the clarifier the same. My pool water is crystal clear. Alkalinity is nearly perfect. I also noticed that when I backwash, the water comes out very dirty. So this stuff works and really cleans any hard water.

I ordered it to sprinkle on tree stumps . Make holes first using a drill. Hoping it will rot them soon so I dig them out with ease and replant soon.
