## Customer Reviews

### ⭐⭐⭐⭐⭐ Controls our algae!!
*by G***S on November 7, 2025*

Good service and a good product for our pond.

### ⭐⭐⭐⭐⭐ Algae
*by J***E on October 18, 2025*

This product works great.

### ⭐⭐⭐⭐ Good Product, Cost Effective for Larger Bodies of Watet
*by L***Y on August 4, 2018*

Good for algae in stock tanks. Effective and versatile for both floating and submerged algae. Takes some trial and error to get the proper mixture for your individual needs. Mixing instructions are overly complex and somewhat difficult to interpret. I felt as if the instructions and mixing guides were written to protect the manufacturer from liability rather than to actually help the consumer. I use Cutrine alone or in combination with diquat depending on the problem which has arisen. Once you get your mixture right Cutrine is an effective, economical treatment. Does not kill Duckweed or Azolla.
