Copper Sulfate Pentahydrate Powder - 5 Lbs.

Add it to my pool to help control algae growth and reduce chlorine consumption

thanks

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

Used this to control algae in my pool as this is the active ingredient in most algaecides. Works great for what I’m doing. If the package was resealable I’d add a star

Bulk Copper Sulfate Powder delivered promptly. Product was packaged in heavy plastic bags inside mailer with no noticeable leakage. Powder was uniform in grain size and easy to mix and dissolve in water.

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.

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.

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