I have had recurring instances this year of heavy amounts of "foam" blanketing my pond. The good news is that it doesn't seem to be bothering fish or plants. However, it is annoying and I'm wondering what might be causing it.
Water chemistry checks out. A little high on Ph at about 8.5, and a little high on amonia at .25. I cleaned my filters and am hoping that helps the amonia. And the most recent outbreak follows a dusting of sodium percarbonate to remove string algae. But it's been over 2 months since the prior dusting and foam has still occurred regularly.
Pond is 1,000 gallons, approximately 6x10, 4 ft deep at maximum depth. Stream and 5 falls are about 30 feet long and drop aggressively and narrowly down a mountain side, roughly 45 degree angle. Lots of aeration in the stream that hits the small pond at the bottom with lots of bubbles. I'll try to upload a video to demonstrate this if anybody thinks that's the issue.
Foam seems to get worse after a neavy rain, which we've been having a fair amount of recently. Acid rain, maybe? We are East of the Appalachian Mntn. border (50 miles) from Tennessee and the TVA coal fired power plants.
Anybody have any idea what's causing this? Pic attached.
Thanks.
