Copper Sulfate Pentahydrate Powder - 5 Lbs.

As described and arrives on time, works great in pool to keep algae at bay in the heat plus in Florida.

product as described excellent

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.

Just what I needed for my pond and the price was good

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.

Get a bag of this, and never buy another bottle of algicide again.1/4 cup in the skimmer is enough for a 10K gallon pool. Good root killer for septic systems too

Easy to use

I had roots growing in my drain field from trees, twice a year l disolve 1lbs of sodium nitrate is a gallon of water and flush it down the commode. That is the same ingredient that is in a little boxes of root killer and three boxes can cost as much as 10 lb of copper sulfate.
