Foam occurs when water is mixed with air or simply that the water gets agitated, either by fish or a waterfall. Excessive accumulation of organic waste in the pond will result in foam on a pond’s surface. Even without fish or plants in the pond you can still build up an excess of organics in the pond. Do a partial water change, replacing 10-25% of the water every few days until the problem is resolved. This will help to dilute any excess organics that are present in the pond. Adding beneficial bacteria, such as Nature’ Defense will help to reduce the organics as well.

Thank you,
Sue

There are no fish or plants in the feature but I am still getting a lot of foam. It is mainly in the ponds, but also in the stream. I use a defoaming agent which works for a day or two then the foam comes back. Any ideas?
