> Are the products of dechlorinators totally benign?
Personally, I dislike the ones with all the slime coat and anti-ammonia
proprietary ingredients. I use the ones that contain just sodium
thiosulfate. Two brands are Mardel's MarChlor and Wardley's ChlorOut.
These are 2-3 drops per gallon and cost me about $5/year even though
I do a lot of water changes. Sodium thiosulphate reacts with chlorine
to eventually produce sodium ion, chloride ion and sulfate ion. Sulfate
is actually a plant nutrient, so no problem there. It works on chloramine
too. The ammonia is immediately consumed by my plants, I suppose.

People who use pythons or hoses usually add the dechlorinator to the
tank before adding the new water. The reaction is almost instantaneous.
