Conditioners & RO Purification
Water conditioners and water purification are two categories which have made it much easier to achieve success with an aquarium at home. Neutralizing chlorine and heavy metals in non purified water is important for the safety of both fish and invertebrates. Using a reverse osmosis or deionization unit will remove nearly everything from tap water, and in fact many fish keepers will have to add some things back into the water. Other water conditioners are meant to solve problems or simulate conditions native to a particular area of the world where a fish would naturally live.
