My pond perimeter is covered in FA from the pond bottom to the water surface. The algae is as deep as 6 feet and covering my man-made SMB spawning beds. I successfully treated the floating FA earlier in the season with Cutrine Plus, and the algae quickly turned brown and disappeared. Now when I spray the surface mats, they just turn brown and stay there. I assume that the FA is still alive and anchored to the bottom and thus not going anywhere.
I did an extensive killing of cattail and rice cutgrass this summer, so I wonder if this has encouraged even more algae growth. I am using Black Dyemond for shading, yet the visibility is 7 feet with a Secchi disk. On the upside, there are thousands of minnows swimming around in the FA. I stocked 3" YP in June, and plan to stock SMB this fall.
Suggestions? I can try to hit the submerged algae with Cutrine Plus with the sprayer wand or try Cutrine Plus granular. Next year I will look into Tilapia.
