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)

If you follow the recommendations for use, Cutrine granulated algaecide is easy to use and gives predictableresults. 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.

I had a very bad case of algae in my pond. I used just 12 lb of this as a test and it worked very well. I just bought another 100 lb to do the entire pond. I will follow up and let everyone know how it works but if the 12 lb bag was it representation of what I should get it I will be very happy. It got rid of all the algae and I can see to the bottom of the pond in the area that I treated. They also have very good technical customer support and are very quick to respond to questions

I've been using Cutrine Plus granular for 3 years in my 1/2 acre swimming hole/pond. It's fantastic! We stock our pond with rainbow trout so I only treat 1/3 of the pond at a time. The pond gets up to 12 feet deep, and most of the pond has a depth of 6 feet or greater, so treating 1/3 of the pond works well for us. We haven't had any trout die. The algae is gone within a day of treatment. Cutrine Plus is truly amazing and a pond-saver. We also use pond dye to help slow down the growth of algae and hydrilla. We use muck remover pellets to keep our shoreline and pond bottom muck-free. We use Dibrox for treating hydrilla. I highly recommend Cutrine Plus for getting rid of algae blooms fast. It's easy to use, and is a must for keeping your pond algae free.

Found this works ok, but you REALLY have to lay it on, if you expect to kill the chara! Pretty expensive though!

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 have a problem with filamentous algae in my farm pond. I have used a combination of liquid and granular Cuterine for 10 years on the advice of my County Agent with good results. Usually, a couple gallons of liquid and a couple bags of granules can keep my pond pretty and healthy all year. I use a heavy-duty agricultural sprayer for the liquid around the edges and a battery powered salt spreader from a boat for the granules on bottom growing algae in the deeper portion according to the recommended schedule and formulas. I also energetically rake all the floating algae nearly daily with a collection of specialized rakes. I have raked up about a dump truck full so far this spring. This spring I have gone through 7 gal. liquid and 8 bags of granules. My pond is a mess, even with my daily maintenance, and I have spent a great deal on chemicals. The pond has both a windmill powered aerator as well as an industrial electric aerator. I am convinced these guys have changed their formula, either to make more money off me, or they are just selling junk now. I am trying to find a new chemical/ system that works.

This was a product I ordered for my pond. After reading the manufacturers precautions regarding distribution of these crystals, I decided not to expose myself to their possible dangers. Not a negative comment, just error on the side of safety.

Tried a lot of products and found this controls growth better by sinking to the bottom of our pond where of course algae bloom starts. Tried spray version but that only kills floating blooms so it reappears shortly.
