Most of the decent de-chlorinators are safe to use and even safe with
overdosing.  Many of them don't use Thiosulphate because there are other
compounds that are safer and perform additional secondary tasks when once
they neutralize the chlorine compounds.

===========================
Which compounds are those? I read that ST is safe even at several times the recommended dosage. What secondary tasks are you referring to?

Chloramine is made of chlorine and ammonia. ST breaks the bond and detoxifies the chlorine but leaves the ammonia. If you have a strong biofilter, lots of plants, low pH, and do small water changes, you can probably use only ST. The tank (or pond in your case) will handle the ammonia. For larger water changes, high pH, or tanks with no plants, it's safer for your fish to use a product that breaks the chloramine bond and detoxifies both chlorine and ammonia like AmQuel or AmmoLock.

Here's an excellent article that details how much ammonia can be in ST treated tapwater. Scroll down to the section labeled "Update."
