Best Aquarium Filter: What Are They?
Aquarium filters are used to remove impurities from water. These include bacteria, algae, protozoa (such as nematodes), viruses and other microorganisms. Some types of aquarium filters are better than others; however, all can be effective at removing unwanted organisms from your aquarium water.
Internal aquarium filtration systems use a pump to move water through a series of chambers or tubes. Water passing through these chambers or tubes is then filtered out. Internal aquarium filters work well for smaller tanks because they do not require much space and are relatively inexpensive to purchase.
They are usually less expensive than external filters, but they may have some drawbacks such as having limited filtering capacity. External filters must be replaced if there is any damage caused by algae growth or other contaminants in the water.
External aquarium filters are generally larger than internal ones and can cost several hundred dollars. They come with various features designed to reduce the amount of time it takes to clean the water, such as UV light units that disinfect the water. External filters can also be very expensive, since they typically need to be installed in a location where sunlight cannot reach.
What Is A Power Filter?
Power filters are similar to internal aquarium filters except they rely on electricity instead of pumps or tubing. They are used for smaller aquariums and can be purchased at most pet or discount stores. They cost considerably less than external filters. Power filters are easy to operate and maintain. Many have attachments that make cleaning them out easy. Some of the better ones even have timers built in so you do not have to worry about remembering to turn them on and off daily.
The only real drawback to purchasing a power filter is that they cannot keep up with larger tanks.
