Straight tap water can’t be used in localities that pipe chlorinated water. In the previous, it was attainable to “situation” the water by merely letting the water stand for a day or two, which allows the chlorine time to dissipate. However, chloramine is now used more often and doesn’t go away the water as readily. Water conditioners formulated to take away chlorine or chloramine are sometimes all that’s needed to make the water ready for Aquarium use.
