Actually goldfish and koi do well in hard water, but lakes are naturally
soft, they
just arent "softened". soft water is stripped of any buffering capacity,
Ca+ and
Mg+. that means the pH will swing wildly and that makes the fish suffer.
in
addition softening strips out chloride ions which are necessary to gill

toxic. http://tinyurl.com/5fsbu9

Hi,
The OP does not state any water parameters and muriatic may not be the
cure. Use muriatic only if KH (alkalinity) is above 200ppm and pH is 9
or above. If KH is low and pH is 9 or above then baking soda will raise
KH and lower pH. Keep adding baking soda (1/3lb per 1000 US gal)each day
until KH reaches 150-200 ppm at which point pH should be about 8.4.
OP's issue is probably moot now, if the problem was fish - killing bad
then it's cured or they're dead.
BTW never saw sodium thioglycolate used to neutralize chlorine,
Chlorine forms pi bond with double bonded carbon?
always
used sodium thiosulphate.
Chlorine forms pi bond with double bonded sulfur?
Not chemist enough to say it won't work just
never heard it being used.

Anybody, anybody?
