Part 1. De-chlorinated water is water that doesn't contain any chlorine.
Part 2. Tap water contains chlorine, the chlorine should be removed from the water before putting in an aquarium. This is because Chlorine is known for cleaning and killing micro-organisms. It should not be put into an aquarium because it can be harmful to the life inside of it.
Part 3. There are various ways to de-chlorinate water. One of the ways is by dissolving a tablet of potassium <span>metabisulfite into it. 1 tablet = 20 gallons of water dechlorinated.
