Chloramine is very stable which is the reason it is used to prevent
bacterial growth in mains water distant from the treatment plant.
The timeframe that I have heard for spontaneous breakdown is 13 days
to three months.
Sodium thiosulfate is used to deal with the chlorine releasing the
ammonia to become breakfast for your hygro. The amount required
depends upon pH -the higher the pH, the less you need. I use two to
three times the recommended level for chlorine. It's cheap.
