Not a good value

Ineffective

I have an acre size pond with a serious string algae problem. I used one bag poured directly into the aerator turbulence. It did not work at all so I didn't try with additional bags. Might work if you have a minor problem. But for me it was a waste of money and time.

Waste of money.

My pond is less than an acre and this product was totally ineffective. In fact the algae got worse within two weeks of the application. It claimed to do a better job than copper, which to me is false advertising. I do not recommend this product. (It's really not even 1 star.)
