## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Product
*by A***R on July 10, 2024*

Lasted for more than 30 days and made our pond look beautiful

### ⭐⭐⭐⭐⭐ It worked
*by B***N on February 25, 2024*

It worked over several applications. Algae was bad so it took several applications..

### ⭐⭐⭐⭐⭐ Highly recommend it!
*by T***Y on January 6, 2021*

This stuff works so well it might be illegal. I mixed 1-gallon with 15-gallons of water and sprayed it from my sprayer mounted in a flat-bottomed boat into my 2-acre pond. Within an hour the visible, suspended algae was gone. In two days the water was clear and the fish more active. Ad says 1-gallon per acre, but 1-gallon in 2-acres of pea-soupy water did the trick for me.
