The name of that stuff is called Sodium Thiosulfate - credit to jlk. She informed me about it... They are like small crystals, you dissolve in water and then this is the liquid used to de-chlorinate. Nearly all branded de-chlorinaters use this ingredient for their product. I haven't used it yet but will be soon when my Purigen needs to recharged... Look it up, very cheap(Ebay, Amazon). It de-chlorinates the water but DOES NOT remove heavy metals. After bleaching(re-charging), use tank water to mix with the de-chlorinater(Sodium Thiosulfate) and NOT water from the tap. So when you need to put the Purigen in de-chlorinater after bleaching you can use this stuff instead of Prime as the water you have used has been already treated for metals. Sorry if that's a bit confusing to others but Phishfriend, you should know what i mean??Please do! I'd like to try it!
PS... I still use Prime for my PWC's, i will only use this to save my Prime(very expensive over here!!)
