Review: Easy to apply and works as advertized. - This product seems expensive at first, but it is worth the price in my opinion. It is concentrated and treats a great deal of water for its size. The real advantage is that it doesn't require and special application. No spaying with droplets of a particular size and no need to be in or on the water. You apply it right out of the container. I do walk the edge of the pond to spread it out a little, but the directions say you don’t even need to do that. It is so soluble it spreads throughout the pond on its own. And it works when applied in the correct quantity and on the right schedule per the application instructions. No more algae.
Review: Seems expensive for size but WORKs - Definitely a very stressful first 14 days. Didn’t notice much difference even with some rain that helped knock down the duckweed. Once I started to see a difference it worked very quickly. 21 days I waited to add the second application by the instructions. I’m currently a week out from third application and the pond has been very clean and duckweed free. Now under the instructions it does state that if your pond has a lot of water change meaning it will have high flow of water through pond from a stream or creek that feeds your pond it will dilute this product too much as it is a slow acting chemical. My situation is pond is currently low as the amount of rain we have received is lower than many years prior. It works very well would highly recommend but be careful of aquatic plants you like it kills everything and will even start to affect cat tails.

### ⭐ Does not work for Alligator weed
*by W***. on June 23, 2024*

I purchased this product about 2 months ago to treat a small, roughly 200 square foot area of Alligator weed. I followed the instructions applying it twice about two-three weeks apart. I used half the bottle the for the first application and the remaining for the second. The weeds initially turned brown, but after only about three-four weeks from the second application, the weeds are already starting to come back. Definitely not worth the $100+ for the small bottle.
