In Nature, fish have an unlimited supply of water. Oceans, lakes, rivers, streams, ponds, etc. and rainfall all contribute to this continue clean, fresh, water supply. However, in captivity we offer our aquatic friends a closed system with a limited amount of reoccurring water available. Therefore, all the food and subsequent waste produced by fish, inverts or decaying plant algae material, slowly pollute the water. Chemical medias help remove such contaminants to keep safe levels between water changes.
