Brown surface on pond water
I was wondering if anyone could give me some advice please.
Since April last year I have had a brown film/scum on the surface of my pond.
The fish and tadpoles are alive. The Lillies are stunted in growth, the leaves are small and brown and not green. The oxygenated weed is not growing and multiplying.
Please could you tell me what the problem may be and how I can rectify it.
