Works as advertised on algae. Kills floating algae in my 2 acre pond. Does not work on sub-surface algae or weeds.

Good Product, Cost Effective for Larger Bodies of Watet
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.

Works FAST!
I applied this to my pond and the next day, it was already showing signs of working. I'll give it a week and see what the results are. So far I'm happy with this product.

Don’t waste your money unless you own a good size lake
I got this algaecide last year thinking of cost effective turn out such a waste of money. I didn’t return it after reading the label though maybe it will last for a while. For 900 gallons back yard pond like mine just need a couple of ounces will do the job even made my koi stressed for a day. I do have UV light with my filtration system so only used twice for the whole season. Spring comes I use it again wow no longer work at all ,only make my koi stressed but the surface of the pond stay green color.Do not recommend to buy this product unless you own a lake and use it all in one season.
