Chloramines remain active in the water system for a considerably long period of time. Like other molecules, chloramines contribute to the total amount of dissolved solids in the water. Like chlorine, chloramines are selectively reactive and may have damaging affects when they remain in the water for too long.
When chloramines are present, there are usually trace amounts of ammonia and hypochlorite in the water as well. Chloramines are hardly ionic. As a result and because of the low molecular weight, chloramines, mainly monochloramine, are difficult to remove from water by reverse osmosis (RO) or water softening. Boiling and distillation cannot be used either. Substances for chlorine removal cannot be used for the removal of chloramines. Sunlight and aeration may aid chloramine removal.
Chloramines can be removed by means of a granular active carbon filter. This filter brings down chloramine concentrations from 1-2 ppm to less than 0,1 ppm. One must make sure that the active carbon comes in contact with chloramines for a significant amount of time. An active carbon filter is a selective, which means it also removes other compounds, such as chlorine (reduction to chloride), hydrogen sulphide, organic compounds, THM, pesticides and radon. When these compounds are present in water, this will influence the capacity of the filter.
The amount of chloramines in the water can be determined by measuring the 'total chlorine' residu. This means measuring the 'total amount of chlorine' or the 'amount of chlorine compounds'.

Thanks for the info. I do have an active carbon as the second stage.... So I should be safe. But during water change, I think I will still add prime from now on. Just incase.
