Review: Worked for my blanketweed - I had tried barley straw and liquid barley extract, which did seem to improve our blanketweed problem somewhat, but I was still pulling quite a bit out. Dumped some of this stuff in the pond a couple of times and within a few weeks, the sheets of slime were gone! A few days after the first treatment, there was a bunch of black stuff at the bottom of the pond, remnants of the blanketweed that was killed off. After a while, since the product is keeping the blanketweed from forming, there's no black stuff either. Very happy with this product.

Does exactly what it says it does

### ⭐⭐⭐⭐ Blanket weed blitz.
*by M***M on 12 March 2025*

I assume the product is ok but it was an incredible challenge to actually open the jar and then after a lot of prodding there was no scoop inside to measure out the quantity required. I am currently waiting for a scoop!
