Hi Everyone
We bought property about 9 years ago. Its a high acid area and the ponds are old and were on the property when we purchased it. This pond is only fed when water is high enough to flow into it from a neighboring pond.. Its always been clear until last year.
The pond does have a high amount of leaves in the bottom from years of neglect. There are no fish and no vegetation,and the water only occasionally reaches the outlet, But it never smells bad. Last year we noticed this scum. Does anyone have a suggestion as to what it might be? Our fear is someone dumped something in it to kill mosquitoes.
thanks
