Ammonia will be handled by the cycling process but are the other two removed by RO/DI?
thanks,

The chlorine and chloramine and many other chemicals are taken care of by the carbon cartridge before the RO membrane - chlorine can severly damage a RO membrane for example, so the initial carbon filtration helps with that. Metallic ions, etc are usually taken out by the membrane and by the DI resin after the RO membrane, hence you don't need Prime.
