## Description

Made in the USA - 10 Lbs. Copper Sulfate Medium Crystals. THIS PRODUCT DOES NOT MEET PPPA REQUIREMENTS AND IS INTENDED FOR INDUSTRIAL AND MANUFACTURING USES ONLY AND IS NOT INTENDED FOR USE IN AREAS WHERE CHILDREN ARE PRESENT.

Review: Works well when used as directed - I bought this 4 yrs ago to treat around septic tank covers to prevent root incursion. I also dissolved in water and sprayed on an asphalt shingle roof to remove mold/mildew/algae stains. It did a great job as, over time, the stains disappeared and have not returned.
Review: Great for killing roots in old pluming (See hints in review) - When I had a plumbing clog, a plumber came and discovered roots in the pipe. He tired to tear them up a bit, but also sold me 2lbs of this and said dump 2lb down the toilet every 6 month to kill the roots. I had to lay $40 for 2lb. I later found this 10lb back for $40 and was quite pleased to buy it at a much better price. After another backup, a better plumber confirmed this was good stuff and I should keep using it. They were amazed at this good price. If you live in an old house with cast iron pipes and large trees around, you might want to do some preventive maintenance. FYI, the good plumber (actually drainage pipe experts) let me know that with my old cast iron pipes, "good" toilet paper like Charmin and Northern, uses lots of glue to make the TP "good". But for old pipes like mine, these can get caught and they won't dissolve for a long time. They had me switch to Angel Soft. I disklike this compared to Northern, but I have to use it. I have also disliked Costco TP, but that is probably because it is "bad" like Angel Soft (and probably cheaper, so I might switch to that).

## Questions & Answers

**Q: How much should i use to put down my house drain for killing roots? do i need to dissolve in hot water first? will be flushing down the toilet. thanks**
A: Your septic tank should be full . You can pour right in the toilet and flush or dissolve on hot water and pour in the toilet. I used the full bag the first time . Then I’d do 1/2 bag every 6 months that will back the roots away from the system. My dad was in the septic tank cleaning business with my brother since 1952 it works

**Q: What is another recommended way to store 10# of copper sulfate?**
A: The only issue is absorbing water as you know. I have used a vacuum seal for long storage. Zip lock bag,  seal and add silica absorbant pack. Lastly, and not recommended if stored next to food, is use of a freezer plus zip lock.

**Q: Are these fine crystals or lager one ?**
A: Fine crystals, it is difficult to describe. Fine as compared to what? Ours were described as fine. Just be sure to stir them enough to liquify.

**Q: What is the 1% inert matter in this product?**
A: No idea. Product performed as advertised but duration not what we hoped for. Maybe we should have used a stronger solution. I
