Cutrine-Plus Granulated Algaecide - 30 lbs. Professional-Grade Algae Killer for Lakes & Ponds, EPA Approved to Control All Types of Algae (Planktonic, Filamentous, and Chara)

Cleared up algae in 48 hours. Treated 1/2 pond, will treat other half in recommended time frame. Have used the product for 2 years.

My 3/4 acre pond had filamentous algae floating around the edges and looked terrible. Our County Agent recommended Cutrine Plus and said to just to treat 1/4 of the pond at a time to avoid killing fish, turtles, frogs, etc. I was nervous using a chemical because I'm an environmentalist and rarely use chemicals. I sprinkled about one pound of Cutrine on the algae. Not much change. I sprinkled another pound a week later. Small improvement. I was thinking it wouldn't work and was afraid I'd have to get a $2500 aereator as a pond maintenance organization recommended. Another week passed and I was going to treat it agan. Lo and Behold....the algae was gone, my fish and turtles were fine and the frogs and tadpoles were too. And I'm happy because the pond is beautiful again.

I treated a 1/3 acre pond and can't say it didn't work because a lot of dead algae floated up from the bottom, but there is still algae in the pond along the sides. In all fairness to the product, this was the first time pond has ever been treated and realize a yearly treatment plan needs to be put in place. The area where it didn't seem to work as well was around the the edges and will probably use a spray for that. In the directions it stated it would treat a 1/2 acre so that is why I gave it 4 stars, because of the edges of the pond. Otherwise, the deeper areas of the pond the algae appears to be reduced or gone. Will treat again per the instructions and stay on a treatment plan.

Works as it says. Good product.

Used it for years. Always get the job done on controlling algae growth

Works great on my shoreline

Bought this for my brother in New Jersey, after he told me of the problems he was having with the algae/ growth in his 3/4 acre pond. Seems that the label lists specific types of growth it is designed to control. I guess what was plaguing his pond wasn't one of those listed because even at the dispursal rate shown, it did not meet his expectations for algae control. Matter 'o fact, it didn't do much at all. +On the plus side; It was shipped in a timely manner at a reasonable rate. -As to the negatives; Be sure what you are trying to control/kill off and see if this product is designed for that growth, specifically, because "it ain't cheap"! A caviat; If it HAD lived up to our expectations it would have been worth the price and then some.

If you follow the recommendations for use, Cutrine granulated algaecide is easy to use and gives predictable results. A hand held spreader made distribution over the surface of my pond convenient. I applied two treatments, two weeks apart, just before spring. I use it as part of a program I came up with that also includes aeration, natural bacteria and the messy job of removal of excess detritus (actually, this method is pretty common). Cutrine jump-starts the process and the aeration and bacteria help metabolize the excess nutrients that result. Cutrine eventually breaks down in sunlight, therefore you may need to reapply it later in the season if you get a bloom. The key is being consistent. The downside is it can get a little expensive.
