Hobbyists have a lot of options today when it comes to choosing saltwater for their reef aquariums. The most common option has traditionally been mixing saltwater at home using carefully developed dry synthetic blends. For hobbyists fortunate to live near the ocean, or a public aquarium, bulk supply of filtered seawater has long been available. In more recent years, it's become possible to even purchase pre-packaged jugs of filtered seawater in local stores, a real convenience for nano reef keepers in particular. Many local fish stores also offer both pre-mixed saltwater and filtered seawater in bulk, allowing you to purchase just the right amount while reusing your own containers.
Let's take a look at where everyone is sourcing their own nano reef aquarium's saltwater. Have you made a switch from one source to another? Share your experiences, good and bad!
