Aquarium Water Neutraliser
All the various aquarium neutralisers you can buy will remove chlorine from tap water. More advanced neutralisers will also provide other beneficial effects for your aquarium. These type of water conditioners are not a necessity, but may be very useful to buy in your particular situation.
Some water authorities also add chloramines to drinking water. Consult with your local council and if chloramines are present choose a water neutraliser that also cancels these chemicals.
