Hello catmandoo,I'm new to the pondboss forum and I'm dealing with a cyanobacteria (blue-green algae)problem and was wondering if you have had any luck or even tried to remove the cyanobacteria? I have started using bacteria to reduce the phosphorous and nitrogen in hopes of treating the problem and not just treating the sympton by using cutrine. I'm getting tired of the viscious cycle of burn down with cutrine only to have a return in the new future. Hope you have cured the blue-green in your pond. If you ever get curious about reading of other blue-green problems... do a search on Grand Lake St. Marys in Ohio
