Small amounts of chlorine and chloramine are added to tap water to kill organisms for safe human consumption. Of course, chlorine and chloramine are toxic to your fishes. Use aquarium chlorine removers to do away with them. Aquarium chlorine removers often remove other harmful heavy metals, ammonia, or otherwise prepare your tap water for aquarium use. You'll also find that our water conditioners and stress relief products tend to remove chlorine as well.
