Over 60 million people have an aquarium.  And it's easy to see why this hobby is still growing fast.  It can be as simple as a goldfish in a bowl on a child's dresser, or as complex as a huge saltwater tank built inot the wall in the living room.  It can be as relaxing or as challenging and rewarding as you want it to be.  Advances in filtration, lighting, and tank design have made it easier than ever to have an awe-inspiring tank that will astonish your friends and family.

There is not much that is more relaxing than watching a beautiful aquarium full of fish as they float across the tank. The sound of the bubbles, the soft light and slow moving brightly-colored fish add to the enchantment of this stimulating hobby.

No matter what level an aquarium you have or want to create, the basics are pretty much the same...

Your aquarium will consist of a tank that holds water, a method to filter impurities out of the water, a heater and maybe a chiller, lights, some kind of decor, and, of course, freshwater or saltwater fish, depending on the kind of tank you put together.
