There are several aspects to this project. I have had little success using GC for algae management. They generally prefer to eat everything else before they eat algae. Also Tilapia are not a magic bullet, I wish they were. There are several management efforts we implore to manage algae. But again they are a symptom first we have to address problem.
Also there are strains of algae that grow in cold water. Once water temps warm up these species will die off and another species will take its place.
You are very close to us. Let's talk about your situation and come up with a solution.
In response to difference between cutrine plus and copper sulfate. Cutrine Plus has chelated copper basically chelated copper is combined with other inert ingredients to keep copper more active during a longer period of time. Usually 10 to 14 days. It will not bind to soil.
Copper Sulfate is very fast acting but any excess copper can become bound in soils. This can disrupt natural cycle and growth of aquatic invertebrates that we hold near and dear.
