Well I did it. Like you guys said I over- fertilized my pond last month and really have been sweating out the possibility of an oxygen problem. After several sunny days and plenty of rainy late afternoons and nights here in Georgia, the clearity is now at 20" plus. My question is this-MY bloom has turned to a brownish color, and I have some green algea floating at the upper end of the pond (depending on wind dir). Should I wait until this has disappeared before I fertilize again or is this a problem? I'm not sure if I sould give the pond more time for the excess alge to die or not?.I surely don't want to make that mistake again. The rest of the pond (5 acres) is a dark brown color but very clear.
