Cutrine Plus Algaecide 1 Gal
Product Review (submitted on July 16, 2012):
We had used copper sulfate to control filamentous algae in our 3 retention ponds with reasonable results but lots of work. We sprayed the bloom then in a day or two we pulled the dead "stuff" out of the water and allowed it to dry on the sides of the ponds for a few days then went back to bag it up for the garbage. Usually there would be signs of needing to treat again just as we were finishing the first process.
Since using Cutrine we no longer have to "harvest" the dead algae - I'm not sure what happens to it. Additionally, we are only treating once a month with minor touch ups in small area _ probably spots we missed.
Great product. Like all these things, I just wish it weren't so expensive.
