I use it for a water feature pond
I have used this product since installing a water feature in my backyard last summer. The water feature tends to cause algae to form on the rocks, so I began using this product to hopefully kill existing algae and prevent further buildup. It does foam at first because of the cascading water feature, but that soon goes away. When all is said and done, it does a good job of limiting algae buildup. Works good for my application.
