I spoke with Aquatic Control today about the Phoslock product and I think it definately may be an option down the road. For now I went back to the old method of just spraying Cutrine Plus. I have my pond algae free after spraying 1.5 gallons across the entire pond. So far nothing has started to bloom back but I have another gallon on hand to spot treat it until I get a permanent solution. One plus was the Cutrine even killed my Sago pond weed or at least burnt it badly to a crisp brown. At this point it has solved all of my problems. The guy at Aquatic Control told me it was perfectly acceptable to spot treat the entire season with the Cutrine product as a long term solution but I'd still like to try to bind the nutrients so rebloom wouldnt happen as often if possible.
