Choosing and Buying a Saltwater Aquarium

The main difference between all aquariums, whether saltwater or freshwater is whether they are made from glass or acrylic. Traditional glass aquariums are cheap and easy to clean. On the other hand, acrylic (e.g. plexiglass) aquariums are stronger and easier to see into than are glass aquariums, and they come in multiple non-traditional shapes and styles. Most glass aquariums have the traditional rectangular design, but acrylic aquariums come in cubic, cylindrical, and octagonal shapes, among others. Many people opt for a glass bowl or vase, but these items are too small to serve as saltwater aquariums.

In general, saltwater fish experts say that the bigger aquarium you have, the better it is for the fish but the more difficult it is for you to maintain. Saltwater aquariums are generally larger than freshwater tanks and regularly range from twenty to fifty-five gallons.

When you choose the size of your aquarium, consider the type of fish you want, as well as the weight of the aquarium itself. A twenty-gallon tank, for example, weighs more than two hundred pounds, so make sure your table, counter or aquarium stand can support that weight. Some people prefer the expensive option of putting saltwater aquariums against, or into, a wall. As long as you make sure your wall can support the weight, placing a large tank against a bearing wall can add support for your tank.

Look for aquariums at pet stores, on the Internet (acrylic aquariums only), and at garage sales. At pet stores, however, you can likely purchase a pre-assembled aquarium, complete with filter, pump, thermometer, and anything else you might need. This package deal adds significantly to the price, but it makes set-up much easier.
