I think it's important to mention that acidic water is the only time ammonium (NH4+) will remain ammonium. Otherwise, in alkaline water, it will revert back to ammonia (NH3).
One of the chemistry people correct me if I am wrong, but ammonium will give up its extra H+ ions in the excess of OH- ions found in alkaline water (to form water and ammonia). So you'd be right back where you started.
