No, the InVade Bio Remediation is not labeedl nor has it been tested for use in ponds for algae control. We would recommend Cutrine Plus Algaecide in ponds with fish to control algae, however this and other algaecides with copper should not be used in ponds with koi, trout, or goldfish. Please be sure to read the product label before use.
