BioSafe- There is a pond locally (NW OH) that is relatively deep, clear water (Vis. 8ft) and growing on the sediments is a bluegreen (Cyanobacteria) algal mat composed primarily of Lyngbya sp which will be called Planktothrix with the new taxonomy standards. These spongy mats which are about 3/4" to 1.25" thick peel off the sediments mostly in August and float like "cow patties" on the surface. When growing on the sediments the mats of this alga seem resistant to CuSO4 and Cutrine. How is the best way to use Greenclean on this problem?. How is GC best spread to get an even coating of the product on the sediments?. How fast should one see effects of the GC if it is going to deter this alga?.
