It is really pretty simple. You add one drop of dechlorinating solution
(sodium thiosulfate) for each gallon of water that has 1-2 ppm chlorine in it. Many
municipal systems use more than that, especially after a heavy rain, so you
need to test the effect or add 5 drops per gallon. The excess thiosulfate will
not hurt the fish but it will take care of any amount of chlorine likely to be
encountered. A test kit is essential to really understand what you are doing
---in-least as a start. You don't need to test every time unless you suspect
(your nose will tell you) an overdose. For source of a very sensitive test kit
and bulk dechlorinator, see

Now if your municipal system adds chloramine, the thiosulfate will
liberate ammonia which is also toxic and can be eliminated by adding Amquel after t
he thiosulfate. Some people neutralize the chlorine and let it sit 24 hours to
help eliminate the ammonia. I prefer to just remove everything with an in line
carbon filter.
