I have algae mats around my shoreline and filamentous algae submersed. I have raked the mats out but it comes right back. I have used Airmax KnockDown along with the Booster Plus. Several applications - some parts of the mats get brown but is not killing it. I also tried Cutrine Plus liquid with no luck. Also used Cutrine Plus granular for the submersed alge with little effect.

Other options? Should I hire someone to come in and spray it all. I have 10 grass carp that are mature and large but they do not seem to be helping anything.

Following good rains there is a small spring that flows through some other ponds above me and into my pond and then flows out of my pond. I thought about using some dye but with the outflow not sure it would help Thanks
