I wouldn't transport the tank with any water in it, if that's what your asking. You need to treat your tap water with a conditioner such as Seachem Prime that will get rid of chlorine and chloramine. Most also detoxify heavy metals, and Prime detoxifies ammonia and nitrite to some extent as well (though it leaves them available for the beneficial bacteria). Chlorine/chloramine are lethal to fish and present in almost all tap water. Heavy metals can be lethal and are sometimes present especially in well water.
