Can anyone help me identify this? After cleaning a greenish colored pond, when the water was clear, a lot of this started developing on top of the algae on the walls of the pond as well as on the water plants. When you touch it, it just breaks apart like its dust or silt. The pond has biodegradable blue dye to help prevent algae blooms, and I have cleaned with the bacteria. They cling to and cover everything that stands still and are brown. And disperse in the water when you touch it.
Any insight would be so helpful.
