Is Charleston Water System water safe for use in aquariums?
Charleston Water System uses trace amounts of chloramines (a mixture of chlorine and ammonia) to disinfect drinking water. This trace disinfectant is harmful to fish and other aquatic life, so you must remove the chloramines to make the water safe for aquatic life. There are a number of products available at pet stores to remove chloramines from your fish tank. Charleston Water System tap water is safe for dogs, cats, and other non-aquatic pets.
