Can I use purified water for my freshwater aquarium?

When making a water change to their aquariums, most owners know better than to use water from the tap directly. Some find that they need to age the water for up to a week in order to achieve complete elimination of the chlorine. They may also have to screen the water through a cloth pre-filter to remove rust, sediment, etc.

You can avoid the above hassles by first running the water through a water purifier. Not only will it efficiently remove chlorine, chemicals, rust, heavy metals and other contaminants, it also makes hard water softer.
