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: Getting rid of submerged vegetation in a pond - Sensational product. I had submerged vegetation covering 95% of my pond. With such ease of adding to the pond within two weeks, 2/3 of the vegetarian was gone. One week later I had no more vegetation, and the water was so much cleaner.

### ⭐⭐⭐⭐⭐ Getting rid of submerged vegetation in a pond

Sensational product. I had submerged vegetation covering 95% of my pond. With such ease of adding to the pond within two weeks, 2/3 of the vegetarian was gone. One week later I had no more vegetation, and the water was so much cleaner.

### ⭐⭐⭐⭐⭐ Works on small pond
*by G***G on July 20, 2024*

I have a small backyard koi pond of approx. 800 gallons that got duckweed a couple of years ago from some plants I had ordered on eBay. This product is expensive but I hadn’t found a better option, so I bought a bottle and did the math to determine that I needed to add a whopping 3 ml. I double checked my work and got the same answer. So I used a syringe that had come with an inkjet refill kit, shook the bottle, sucked 3 ml out, and squirted it into the pond. It remained kind of congealed so I did mix it into the water. A week later and the duckweed turned light in color and started to die off. I skimmed most of it off and it’s obvious that it is no longer spreading. I’ll reapply in a couple of weeks per the directions but I stand amazed that 3 ml was this effective. It does not appear to be affecting my 3 koi at all.
