Pond Boss Forums GENERAL QUESTIONS Muddy water Stained Water / No Algae Growth

Shawn, I think you are spot on with your assessment. We received major rain in July, and a lot of ponds were filled by runoff through wooded lands, and the ponds are now stained brown with tannic acid. Visibility is still running about 30" even though the rain stopped well over a month ago.

I'd be willing to bet that if the water was tested for total P, Ortho P, Nitrogen, alkalinity and hardness, the answer would be very apparent.
