All About Saltwater Aquariums

Creating A Saltwater Aquarium

It is true that saltwater aquariums can be a little more difficult to maintain and set up than a tropical freshwater aquarium tank. But don’t let this hold you back. With the correct knowledge you’ll be able to set up an awesome saltwater aquarium tank.


There are three saltwater aquarium tank configurations:

  • Reef tanks
  • Fish only
  • Fish only with live rock (also known as FOWLR).

Reef tanks are made up mostly with invertebrates, corals and anemones. Of course, fish can also be placed in this type of tank, but they generally are not the main focus for this type of aquarium tank. Coral can be expensive but once you know how to keep it, your money outlay can be delegated to extra coral purchases to enhance the tank.

A fish only tank, contrary to popular belief, can actually be the most challenging one to create. Since there is no ecosystem created with rocks and corals you have to attend to the tank carefully and keep the water changed out as well.

A FOWLR (fish only with live rock) tank generally needs better aquarium lighting. With live rock as well as the fish, there is an ecosystem that will be more self maintaining. This is a good place to start with saltwater aquariums.

Regardless of which type of tank you choose, do your research. Your saltwater aquarium will become a life long hobby. Create your saltwater aquarium correctly from the start and you will get years of enjoyment from it.
