Works well on curly leaf pondweed
Seems to work on curly leaf pondweed -- especially when treated early enough (about 50F water temp).

Handling Invasive Aquatic Species
The product works as intended. It is extremely important to follow instructions and receive authorization for use from State Authorities before using.

Pond Problem Solver
Cleared out stubborn algae in just a few days. Easy to spread and works fast without harming the fish.

Weeds gone
Why did you pick this product vs others?: Works great on lake weeds. Unfortunately expensive and takes a full bag to do the job.

Very Disappointed
I bought two 20 lbs bags to distribute on these small areas on May 15th. As of right now it's June 9th and the product hasn't started, stopped or been of any boundary to the plant life in my pond. Ha ha ha ha Man, I don't even know what to say, it honestly looks like the plant life started to grow even more! I had high hopes for this product but it has just let me down.

Does okay
This is my second bag of this. I use to control weeds off the dock in Minnesota. Seems to do a good job when applied early in the spring then reapplied a few weeks later. Does not help with tougher plants like cattails.
