In my last blog, "Algae: A Pond Owner's Nighmare," I described how frustrated I was with my own koi pond. Well, I am happy to report that things are much better! After ordering new filter material, which I clean several times a day, and using the Koi clay, the only place I have algae growing is along the edge of the liner. Through trial and error, I found that if I sprinkled the clay directly on top of the algae, the next day there appears to be much less. Another bonus: my koi, which I've had over ten years, seem much happier, which makes me happy, too!
