Hi Alex,
A couple of thoughts.
Do you think that the pond is getting runoff from the lawn when it rains
so
hard?

The ponds edging stone is slanted away from the pond so any rain water tends
to run away. Of course, the exception is rain that falls directly into it.

And is there fertilizer or herbicide on the lawn? Other than the edging of
'indian stone', only 20mm decorative gravel is nearby.


Do you have a mech/bio filter running on the pond?
No, I was hoping that good combination of plants would do the trick. It is
only a comparitively small pond - 7ft - 4ft, by 20 inches deep (with shelves
for the plants.

There were originally 9 (now 7!) 2 1/2 inch sarasa comets in it.


You can read the algae primer for tips on your murky green water in the

I'll let others answer questions about salt.

Hope we can track down your problem!
