can time clean

can the average tap-water return to a condition that will allow fish to thrive, if it is left to sit undisturbed ? and if not is the only practical method adding more of something. I wonder about chlorine and other chemicals that are blended in that filters don't stop

Chlorine is eventually given up, boiling will accelerate the process plus kill any pathogens (bugs) the pH may need adjusting and air bubbling through to give sufficient oxygen.

Check out Hydrogen Peroxide ( food grade 35% ). Reverse osmosis filtration along with UVC light is said to remove pathogens also.

...except that Hydrogen Peroxide in significant concentrations causes quick skin deterioration in humans, and will probably kill fish.

The poster was interested in removing free chlorine from water. The simplest way to do this is to pass the water through a granulated activated carbon filter; chlorine is thereby converted to chloride. Once downstream of the filter the biological protection afforded to the water by the chlorine, thereby rendering it fit to drink as a result of protecting the pipeline through which it is supplied, is lost. Biologial activity can then proceed unchecked unless other measures are taken to discourage it.
