Our tank is vented. We do not have the sulphur smell in our water, but those around us that do have found the tank alleviates it. It may depend on how the tank is vented. Chloramine may outgas with time, I know for my reef tank I have to use a carbon block designed for chloramines when on municipal water systems. It was my understanding from a chemist that it did not outgas but did change formulation.
