Homemade dechlorinator

[Transcriptus]

Greetings All -

I have gone through the aquarium newsgroups to find the proper mix for a homemade dechlorinator to use in my tanks. It appears that there's a convention of chemists inhabiting the newsgroups!

Can anyone offer the recipe - in layman's terms - for mixing Sodium Thiosulphate with water to make my own dechlorinator?

Thanks in advance.
