dechlorinating water

I cannot find sodium thiosulfate (by itself) anywhere. All the fish stores sell for chlorine eliminators also include "other" shit like hormones, and a conditioner to help build up the fishes protective slime coat.
So, my question is.... Are these products OK to use? Or am I just as well to bubble the chlorine out? I think that bubbling would get rid of the chlorine in about 24 hrs. My water tank is really tall and narrow, so there is more water volume than surface interface, and that surface interface is where the gas exchange takes place. I am probably answering my own question here, I just want you guys/gals input.
Thanx.

I let my water sit for 24 hrs and that does the trick. Bubbles will certainly help.

i bubble mine in a 30 gallon trash can for 24 hours to prep it. i use this as straight water after i check ph. mine is usually a little high. Once i ph my water to 6.5 i dont touch it again after i mix my earth juice feed. I dont know about other organic feed but EJ will self correct its ph.
