20 years of yellow mustard algae -- GONE and still GONE
This is the same stuff in PoolRx (which is how I learned about copper sulfate, the PoolRx product works). Used appropriately like you do and should with any pool chemical, this is way cheaper and may be of lifetime supply as my 26,000 gallon pool barely needs any maybe once a year. I used to brush yellow mustard algae weekly if not daily and no use of Yellow Out or anything ever really got rid of it. PoolRx did and we're algae-free going on three years, it's just that I only use the copper sulfate if I see a hint of yellow. No need to buy PoolRx anymore (sorry for sharing your secret, I'm sure PoolRx has other qualities).

Kills plants
I had a wisteria bush destroying a fence. Through a bunch of this on it and it was pretty much dead in 2 days. I finished off the wisteria bush with a little brush killer. This particular section of my yard I want nothing to ever grow

Not even remotely pure.
Claims 99% purity but it's really dirty, I had dead bugs in one bottle, and it's oxidized pretty bad too because they don't store it in an air tight container.
