Crystal Blue Pond Booster

I live on SC's Sea Islands. My pond is plus or minus 1 acre with controlling depth of eight feet. An organge/green algae was taking over the pond the water was clear. In early June, I poured one gallon of Crystal Blue Pond Booster around the edges of the pond. It began to work in a couple of days and within three weeks, the algae was gone. A month and a half later the pond is clear of algae and a beautiful blue. It has not harmed the wildlife. I am delighted with the price. I have paid much more for different products that did not work nearly as well. I will use it again in the fall.
