Hello,
I have just started a new pond, my first one becoming too small for the
fish. I was advised to add salt to the new pond as a preventative for
stress when moving the fish. However, I have a problem with green water
now, and wonder if the biofilter is effected by the salt, in other
words, does the salt kill the beneficial bacteria? The water tests
with zero ammonia, zero nitrite and zero nitrates, but then it is 1200
gallons with only 5 goldfish and 5 koi (about 12 inches each). So what
could possibly be the reason for such green water? I have about 2/3
shade most of the day, and lots of under water plants, water lilies and
tall grasses. The biofilters have been cycling for about a month now,
and I have added several bottles of PondCare BioStarter. Any advice on
the salt question would be appreciated. Please reply to my email:

Thanks very much in advance.
