My pond has been running for 2 years and water is clear. But the last few days i have had a oil-like green stuff on the surface, it also smells. It looks a bit like last year when a neighbour sprayed his fence panels and the overspray landed on my pond, it wasnt green then but this time it is.I would be grateful for any help on this matter.
