Probably a dead bird/animal in there.
I agree. Over years I've found a large floating rat and skeletons of
several small birds drowned in ours. Apparently victims of fatal nosiness.

Thanks for the suggestions folks. No, nothing in there except a mossy type
Lichen of the roof of the house.
Now drained with the tap open and it can stay like that until the Spring.
