Fresh water is naturally occurring water on Earth's surface in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers and streams, and underground as groundwater in aquifers and underground streams. Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids. The term specifically excludes seawater and brackish water although it does include mineral-rich waters such as chalybeate springs. The term "sweet water" (from Spanish "agua dulce") has been used to describe fresh water in contrast to salt water. The term fresh water does not have the same meaning as potable water. Much surface fresh water and some ground water are unsuitable for drinking without some form of purification because of the presence of chemical or biological contaminants.
Scientifically, fresh water habitats are divided into lentic systems, which are the stillwaters including ponds, lakes, swamps and mires; lotic systems, which are running water; and groundwater which flows in rocks and aquifers. There is, in addition, a zone which bridges between groundwater and lotic systems, which is the hyporheic zone, which underlies many larger rivers and can contain substantially more water than is seen in the open channel. It may also be in direct contact with the underlying underground water. The majority of fresh water is in icecaps.
We have a lot of water on Earth, but we also can't actually drink much of it... or use it for farming. That's because most of the water on Earth is saltwater. We humans, like a lot of living things, need freshwater to survive.

Just some thoughts on going from freshwater for the longest time to saltwater for the first time. So far it has been very fun to learn new things. I challenge everyone to start their first salt tank for this brand new year.
Adding salt to your fresh water aquarium can be very beneficial for the health of your fish. Watch this video from About.com to learn more tips for using salt in freshwater aquariums.
