I tend to agree that the peroxygen products such as Green Clean Pro -Phycomycin are not as effective especially on filamentous algae as the copper based products, however the peroxygen products do not add any heavy metals to the pond ecosystem. IMO and in the long term of pond aging and overall ecosystem health years from now the peroxygen products are much better when used early in algae development, correct placement and correct method of application. Green Clean and Green Clean Pro are two different strengths of products with GC Pro being significantly more concentrated. Keep in mind that peroxygen breaks down into water, oxygen and carbonate where as the copper in the Cutrine and other similar products leaves heavy metal bound residue in the sediments that will accumulate with usage. Bound copper products will periodically dissolve during certain sediment water chemistries.
