For decades, the quintessential aquarium system for both freshwater and marine hobbyists in North America has been based on submerged, aerobic filtration using internal or external mechanical filters and/or the undergravel filter. Oxygenated aquarium water flows continually through these filters, and biological activity occurs in the filter media or the gravel. Early versions relied on airstones to lift and circulate water, while most contemporary equipment is powered by compact water pumps or powerheads. Such filters are simple and workable for lightly stocked aquariums, but, unless carefully maintained, are prone to clogging with detritus and sometimes dramatic fluctuations of water quality when cleaning sessions remove or disrupt the colonies of beneficial bacteria in the media.

The word aquarium originates from the ancient Latin language, aqua meaning water and the suffix rium meaning place or building. Aquariums are beautiful and look good anywhere! Home aquariums are becoming more and more popular, it is a hobby that many people are flocking too and fish shops are on the rise. Fish are generally easy to keep although do they need quite a bit of attention. Puppies and kittens were the typical pet but now fish are becoming more and more frequent in house holds. In recent years fish shops have noticed a great increase in the rise of people wanting to purchase aquariums and fish, the boom has been great for local shops as the fish industry hasnt been such a great industry before now.
