Copper Sulfate Pentahydrate 99.9% Crystals - 10 Lbs.

I’ve been using this copper to keep tree roots out of my sewer lines and I haven’t had any problems since I started putting a couple of tablespoons in the toilet. Works great and is much better option than rodding out the line. Great product Get the larger crystals rather than the powder for roots.

I've used Coper Sulfate for 20+ years in my 1/3 acre pond. I have never had such success as I've had with this product. It takes much less product than the box store brand. It dissolves quickly and is very high quality. I am using so much less, that it is saving me money and the pond looks great! Highly recommend it.

Works better than the small granules sold elsewhere---Gets lodged in the drain rather than washing away with each flush

Used this product to unclog roots from yard drain and worked well.

Product arrived quickly, very well packaged with extra padding to prevent accidental cutting into the bag when opening box. Good price. I plan to use this to detour roots getting into my exterior drains, as well as keeping my septic exit free of roots. Thank you!

This is a very good product to kill tree roots that destroy ground items, such drive ways walk ways and patios I myself like the fact that it dissolves easly keeps roots away for long periods of time, and it's easy to use. Great product

Use to keep tree roots from growing in sewer pipes!

Great quality I use this every year along with 1-2 chorine tablets a week to keep a clear algae free pool
