Versatile Copper Sulfate That Delivers Serious ResultsAlpha Chemicals’ Copper Sulfate Pentahydrate is one of those old-school, multipurpose compounds that still earns its place in the shed. The fine powder dissolves quickly and evenly, making it easy to mix for different applications — from controlling algae in pools and ponds to keeping tree roots from invading sewer lines or even for copper crystal-growing experiments. The resealable bag keeps it dry, and the brilliant blue color is unmistakable proof of its purity.Performance-wise, it works exactly as expected. Used in small doses, it clears stubborn algae blooms fast and can help sanitize water systems without staining or leaving residue when properly dissolved. It’s also a strong root deterrent when flushed down pipes in solution …

Really like this stuff and seems to be working well. My main sewer line has a bad root problem, all 90' of it and would backup on a regular basis every three months. Since I have started using this, I haven't had to call for sewer service in 18 months. I know I will have to someday because I am certain it is not reaching the end of line where it turns into the city line (90ft away) where I have a really bad root problem next to a maple tree. I try and get 3 applications out of this 5 pound bag but I also mix it with other additives like foaming root killer (believe its a salt additive) and another foaming additive I get at menards cheap to make sure it climbs up onto the roots. Don't use this by itself, it won't reach roots, you absolutely need foaming additives. This concoction seems to …

I bought this to grow crystals on various objects and it performed beautifully! I made a mistake though. Once I got the seed crystals I needed the remaining solution was left to sit on a plate in my work area. I got busy...Some Time Later - I needed that spot for another project and discovered that the solution kept pumping out tiny little crystals which have migrated over the edge of the plate and onto other things. I am cleaning that up with protective gear on and a friend stops by because they haven't seen me in awhile to find me wheezing through a facemask while shuffling blue crystals around my shop.Good product.

I know that this is not listed for Swimming Pool. I am writing this review because no other post were Saying you can use this in a Swimming Pool. It is the Same Active Chemical used in those little Yellow out and Green out Packages that you buy to Clear algae but less than half the cost and you get a lot more active ingredient.I did not plan on swimming in the Pool I brought back to Service for a while and until the PH Settles in at a Safe Level to Swim, So if you have a Severe Algae Problem such as I had, I highly recommend buying this and Sprinkling it around the Pool with Algae problems. Follow up with a couple of Pool Shock Chlorine Bags. The Day after you do that, you will See a Huge difference, and then as the Algae Dies and gets caught in your Pool Filter, Just Keep Cleaning the …

I chose the product based on prior customer reviews and price quantity maximized. It is commonly known and used as tree root kill amongst other uses so I anticipate it will do what is needed and keep a potential sewer line problem from developing; kind of thing that satisfaction occurs in a somewhat passive manner with no bad things occurring in future based on using the product..
