Good stuff and best price for it is amazon.
Stuff works and best price for it is Amazon. You have to reapply it im a month or two if thick moss on top but worth it cause it really works. Saved our pond from suffocation.

works great
it works amazing for top surface weeds. But it doesn’t kill the root. Reapplying will eventually kill the weeds

Very efective.
This stuff is a little pricey, but you don't need much per batch so it will go a long way. I used it on dry ground. Works very well. The directions say to completely cover the target and that is what I did. Any plants not covered completely will still survive.

Extremely overgrown weeds
Seems to kill surface weeds well, have not noticed any subsurface weeds dieing , weeds were heavy, going to spray again

Works fast
I think this is a good value. I've used this on pond and land weeds. It has great knock down power but doesn't kill roots. However it kills any vegetation it contacts in 24-48 hours. My pond was 99% covered in Duck weed! We'd been treating with copper sulfate every 2 weeks and it still came in and took over. I spray this as soon as I see new growth. New growth slowed down and finally stopped. Need a 1 1/2 stronger solution than the instructions for aquatic. Duck weed is tough stuff. Use surfactant too. And it didn't hurt the fish. I also always use a glove and mask, etc. Better to be safe.

Do NOT use if you have koi!!!!
Do NOT use this product if you have koi!!! We have used this product in the past with no issues to our fish. However at the end of summer last year we got some beautiful sweet koi fish. We have been having crazy amounts of duck weed so we decided to treat the pond once again and this morning I woke up to all my beautiful babies dead. I am beyond devastated and heartbroken. It says that it's safe for all aquatic life but that statement is false. I wish I have just felt with the duck weed now

Helped, but did not solve the problem
It worked okay, but not as quickly or completely as I liked. I used this with the recommended surfactant, and I used them on floating plants (not water lilies...but some other broad leafed plant) that has a stem that runs all the way to the bottom of the pond. It did reduce the number of plants that I needed to remove...and I ended up clearing all of them out by cutting them .
