It's not the liquid form, it's the *kind* of treatment. Kordon makes
"Novaqua," which is an old dechlor-type product made with hypo. It doesn't
appear to kill inverts. They also make "Amquel" which is aimed directly at
chloramine and absorbs ammonia. The absorber is a formaldehyde-like
substance that does (at least in stronger doses) kill Daphnia, Ostracods,
Mosquito Larvae, Hydra, etc.
Mach Fukada first told us of this, and I have subsequently tested several of
the dechloraminators, and found that they all work about the same.
The danger is confusing the old dechlor products with the newer dechloramine
materials. A mistake here has proven disastrous to many fishrooms,
particularly those that do really major water changes.
Since I assumed that different critters would respond differently, just as
Ostracods were less sensitive than Daphnia, I never ran tests of what
concentration killed which rotifer or paramecia. I just eliminated "Amquel"
o/e from waters that would involve baby fish.
