Tap Water

Properly treat all tap water before adding it to your aquarium. Most municipal water contains such added chemicals as chlorine or chloramine to make it safe for human consumption. These substances are toxic to fish and can weaken, damage or even kill fish. Use bottled water, reverse osmosis water, or a water conditioner to remove these harmful compounds. It is also recomended to test your tap water and use chemicals to adjust these dangerous elements if you do not use a reverse osmosis filter. It is also best to let tap water de-gas by sitting in an open top container for a few hours before adding to the aquarium.
