My take on this is that YMMV.  What works in one area may not work in all
others.  From my perspective, while I was living in Honolulu, both
chlorine and chloramine was not a problem.  I never had to treat my
changing water in any way.  Just hook up the hose and fill up the tank.
No chlorine.  It did help that one of our Honolulu Aquarium Society
members was the water chemist for the Board of Water Supply.  Hypo and
Amquel were unnecessary.  Of course back then it wa sall well or aquifer
water. Even back then there were differences in the various locations
onthe island.  There was significantly more chlorine in some areas of the
island.  I tmay have changed as EPA had mandated the addition of Chlorine.

Now in Kula, it is a different story.  Our water is surface water.  IT is
treated with chlorine and the ammount varies depending on prevailing
weather conditions (drought or flash floods) there are times that it is
almost undetectible and otehr that it is very strong smelling.  Now days I
need to filter the water in a carbon, inline filter system to remove most
of the chlorine and I do make an effort to use the thiosulfate on
occasions.  I still stay away from AmQuel as it still causes problems with
killing Daphnia and Moina.  I have wondered about this and some peope see
the same phenomenon and others do not.  I wonder if it has to do with the
over all make up of the water to start with.  My water from the tap is
about 27 ppm TDS, soft and acid and no chloramines.  Maybe in water with
chloramines the toxic effects to Daphnia and Moina are mitigated, by the
over all remaining activity of the AmQuel being lessened....
