Hi all. This is my first time posting here, and I have a couple of
specific questions which I'll ask in separate posts . . .

I had fish die from (according to my local pond outfit) "mouth rot"
(see my next post).

After researching online, I learned that treating the pond with salt
is one of a couple of recommended procedures to help control the
disease in fish.

For the moment, I opted to use the malachite green product instead
(although I did ad 1/4 of the recommended salt dose to the pond as
well), and here's why I'm afraid to use salt:

Not only does it make the environment unfriendly to plants in the pond
to a greater or lesser degree, but it also creates a water disposal
problem for me . . .

Until my fish got sick, whenever I cleaned the filters or took water
out of the pond, I felt comfortable using the water to irrigate my
garden plants. I am in California, and I always try to be water
conscious. Plus the gunk form the filters is supposed to be
organically favorable, and (I supposed) good for plants.

Once I add salt to the ponds, doesn't the water become dangerous for
use in irrigation? Will it gradually collect in my clay soils and make
them toxic to my garden? If that's the case, is it legal to dispose of
the water down the toilet? Or pump it into street drains? What the
heck do I do with it?

For that matter, what about the malachite green? What is the
consequence of disposing this as irrigation/fertilization of yard
plants/lawn? Is it legally disposable into municipal sewer or storm
drains?

If the answer to all of the above is no, then what the heck do I do
with it?

Thanks!
