When you use carbon, there is no need for Repti-safe or dechlorinators or conditioners... as you said the chlorine and chloramines are removed by carbon. Repti-safe and other water conditioners are not recommended as they have harmful chemicals in them.
Purigen doesn't really help with chlorine and chloramines, but will get other impurities. It's great that you can regenerate it for repeated use but it does not replace carbon.

Here's the psuedo MSDS sheet for ReptiSafe

Unfortunately the companies that produce these products are not required to disclose all of the information about them. Using phrases like "propietary chemical or substance" get's them from disclosing what's actually in the product.
Fortunately, there are a few very honest companies like API that do a full disclosure of their chemicals and a proper MSDS sheet. Sodium Theosulfate is the common universal chemical in aquarium water conditioners.
API water conditioner
Here's a few highlights...
SODIUM THIOSULFATE: ■ Very toxic to aquatic organisms.
■ Sulfide ion is very toxic to aquatic life, threshold concentration for fresh or saltwater fish is 0.5ppm. The product therefore is very toxic to aquatic life.
Harmful to aquatic organisms. May cause long term adverse effects in the aquatic environment.

I don't know the exact amount you should use, and the different brands might call for different amounts. The box should come with instructions, but I just put in a medium bag and that's it.... it's roughly 2/3 of a cup.
