Copper Sulfate Crystals-10lb Bag (FINE Crystals)

Seems to work. No clogs from roots since I started using it regularly.

Worked as it's supposed to

Good price and no lumps. Packaged in good plastic bag.

I flush a cup down once every few weeks. Seems to work fine keeping tree roots from the sewer line clear.

Fine crystals easily dissolve.

I used these on live roots when I was digging my French drain. Was easy to apply and spread around. Hopefully it’ll prevent roots, if not I’ll update my review.

Tried a variety of methods and didn’t want to start using $75 bottles of pond clear products. About half a cup in a gallon of water controls algae for 7-10 days. We have no fish or plants so this is an economical and effective solution. Very pleased with it.

I have used cooper sulfate in my inground people before but never this brand. I ordered because of the price and the amount you get in the Bag and I just figured that I would refill the container that I had. But this copper sulfate, I am not happy with at all although it's much finer particles it's left a horrible film in my pool like oily and I have blue particles floating in my water almost like plastic. I know it's this brand product. Don't recommend this one if you using for pool water treatments. As I seen in other reviews I will use this in my septic tank/toilets for root killing.
