homeade dechlor

I'd be careful when using straight sodium thiosulfate. It WILL reduce your pH. In fact, Wardly sells it, in crystalline form, precisely for that purpose.

HCl (hydrochloric acid) is a product of the reaction with Na2S2O3 and Cl2 (chlorine).
 
sodium thiosulfate shouldn't reduce ph to any significant extent if you have any buffer(kh) at all in your water. the amount of chlorine in your water and the amount of sodium thiosulfate you add are both so small that it won't make much of a difference at all.

Then why doesn't the store bought stuff have a "use within 30 days" notice on it?

I can't say, though it's usually sold in opaque bottles. I know form my photography experience that in a brown bottle with a tightly sealed lid, fixer (hypo (sodium thiosulfate) and other stuff) has a very long shelf life. about 6 months to a year depending on how full the bottle is. not sure about the differences in potency required for photography and for dechlorination though. I'd assume dechlorination requires even less potency than photography processes, I may be wrong though. The main cause of early death for photographic fixer is saturation with silver salts.

does anybody know what it decomposes to when exposed to light/air?
 
crystal sodium thiosulphate

I use 1 oz of crystals in 1 quart of distilled water, dosage 1 drop per gallon. I keep it in a small opaque container and the big quart is under the sink.

I've got more than enough, Can sell you some if you wish.

I would not use it for chloramines, the freed ammonia is not good for fish.
 
chico,
I see why you became a senior member so quickly - great responses. Being 16, your liable to become a rocket scientist some day!!!
 
I've kept mine for over a year with no apparent loss of efficacy.

I also have never noticed any affect on pH from the tiny amount needed to dechlorinate.

haha, thank you. right now I'm kinda trying to figure out what I want to do with my life... rocket science might not be bad:p Oh and by the way, I'm a señor member, hehe;)
 
LOL. My apologies 'Señor' member!!
