Hi

We have a pond which ha been self sustaining for twenty years. No
filters or pumps, just pond plants and regular cleaning out of debris.
The fish are healthy and we have only ever lost one occasionally to
what we have assumed to be old age!.

The water has recently turned a milky colour and this has not happened
before. The fish seem OK but is there anything I should be doing to
correct this?.

Alan
