The cleanliness of your fish tank water is constantly being compromised due to various events that happen in this closed environment. Examples of such events are pollution from fish waste and uneaten fish food, detritus from decomposing dead fish and plants, and changes in water composition such as shifts in pH levels and addition of medicines or new tap water.

Fish tank filters are necessary to make sure that the conditions needed for the fish to stay healthy and thrive are maintained. By providing mechanical, chemical, and biological filtration, these filters will remove pollutants and keep the water in your fish tank clean at all times.

Filter types: brief descriptions and the pros and cons

The type of filter you will need will basically be dictated by the size of your tank. Fish tank filters perform either mechanical, chemical, or biological filtration. Some types combine two or all filtration methods.

For small- to medium-sized tanks, you may use hang-on filters, box or corner filters, internal power filters, diatom filters, and sponge filters. Hang-on filters are named as such since they are made to hang outside of your tank. They provide all types of filtration. Box or corner filters are placed in the corner of your tank, providing mechanical and chemical filtration. Internal power filters are normally used inside of freshwater tanks with low water levels. If you want to have fish tank filters that will give the best mechanical filtration available, the diatomaceous earth inside the diatom filters will do the job. Meanwhile, sponge filters will give you good mechanical and biological filtration at the lowest cost.

The filters mentioned above are both inexpensive, simple to set up, and easy to clean and maintain. They are ideal for beginners who wish to start with small tanks and small fish population. These filters can also be used in larger tanks but only as backup or secondary filters, or else they will get clogged up easily.

If you are looking for more powerful fish tank filters, you may want to consider buying canister filters, undergravel filters, wet/dry filters, and fluidized bed filters. The first three types can provide a complete three-step filtration system to your fish tank. While fluidized bed filters do not contain necessary mechanism for mechanical filtration, their biological and chemical filtration capabilities are good for tanks with live plants and heavy bio-loads.

Commonly used filter accessories

Your fish tank filters have parts or accessories that you need to replace regularly. Most filters have filter cartridges. These have to be replaced regularly. Otherwise, toxins will leak back into the aquarium.

Other filters use filter bags and loose filter media. The bags have different mesh sizes corresponding to the size of the media to be placed inside. Examples of filter media are filter gravel, carbon pillows, and bio balls.

It must make any aquarium enthusiast cringe, having to feed his fish every day in the same water that they swim in, breathe in and release their bodily wastes in. If it were not for reasons of yuckiness that that such a situation could not be allowed, it would certainly be objectionable for the way this would poison the water and make it incapable of sustaining aquatic life. How do you treat your fish to a better life then? If the fish lived in a natural water body, a pond or stream, there would be enough clean water in the system that all the bodily waste would not make a difference; in a closed water body like an aquarium, it comes down to the owner of the aquarium to do something to constantly clean and freshen the water the fish live in, to give them a reasonable standard of living. Aquarium filters are the answer; though there are so many, they can hardly be called one answer.

The empathetic aquarium owner must worry most about the health implications of having his fish swimming around in a weak solution of their own bodily waste. What must all the bacteria and other pathogens in the water do to the fish? Do their eyes sting; do they breathe with difficulty in such a toxic water cocktail? Biological aquarium filters are the solution to such concerns. A biological filter is a unit that encourages the growth of beneficial bacteria inside it. These bacteria subsist on the bodily waste of fish; and they break down the poisonous ammonia in the waste into nitrogen compounds, nitrites and nitrates and these are a great way to take the sting out of the problem.

Under-gravel filters are a great example of biological aquarium filters; they're not marketed as effectively these days, owing to the fact that they are simple to build, and offer no opportunity for a killer markup, but are very effective. The idea is that the filter is placed under the bed of the aquarium; water is drawn through the gravel over the bed; the gravel filters out a large part of the suspended debris, and the bacteria that live in the gravel take care of the ammonia. The water is drawn down and sent back up after purification by message of an air stone or a powerhead.

One of the best options that modern aquarium filter technology provides is the canister filter. Canister aquarium filters force the water in an aquarium through a variety of filters and cycle the entire contents of an aquarium every hour. The result is a visibly bright and clean and aquarium that manages to be free of most kinds of impurities. A minor drawback to this type of aquarium filter is the way it keeps drawing all the water through its system constantly; this action creates quite a strong current in the tank that can be annoying to some fish.

One of the most satisfying kinds of aquarium filter to use is the sump variety. Basically a sump aquarium filter is a large aquarium-like tank by itself, used exclusively for water purification in the main tank. The sump is sectioned off into three or four areas, each one installed with a different kind of water purification system. These aquarium filters are mostly the domain of experienced do-it-yourselfers; you could have a sump with a compartment for beneficial plants, one for gravel and charcoal purification, and so on. It is easy to be bitten by the purification bug and let it run away with you though. The final test of how successful your attempts are, rests in the health of your fish population. If your veterinarian certifies them to be as healthy as can be, there's no reason why you should not congratulate yourself on a job well done.

Aquarium canister filters are needed in order to maintain the balance and cleanliness of the aquarium. This type of canister filters may be used for either a freshwater or saltwater aquarium. Depending on the type of canister filter, it may contain media that may filter the water through mechanical, chemical, or biological means.

The canister filters and the hang-on type of filters are comparable in the way they look and perform their functions. However, one of their major differences is that the canister filter may be placed in different locations in the aquarium. Aside from hanging the canister filter, it may also be placed below the aquarium, which will allow you to improve the aesthetic appeal of the aquarium. It may also be placed inside the aquarium. This type of water filter is also referred to as ?submersible filter.? Because of the improved filtration mechanisms of the canister filter, this is usually recommended for those aquariums that have messy eaters that tend to produce a lot of waste.

One of the best advantages of having a canister filter is that it has a larger capacity compared with other filters. Despite the large capacity, it is more compact so you can hide it from view, if you would like to. On the other hand, one of the disadvantages of using canister filters is that they have to be frequently cleaned. This is because the filtration relies on mechanical means. The filtration device will be easily clogged up by the filtered wastes and these have to be removed as soon as possible to prevent the decaying matter to come back into the water.

For this filter, the water is pumped at regular speeds into the filter. The filter usually performs its task using mechanical filters, such as a micron filter cartridge or glass wool. After the mechanical filtration stage, the water is then allowed to pass through different layers of media, including carbon and other absorbents. This will trap the odor, chlorine, ammonia, and other unnecessary chemicals that are in the water.

The canister filter has three types of filtration device. First, the water is allowed to pass the mechanical filter, which usually has the glass wool or the micron filter cartridge. This will filter the solid wastes in the water. Next, the water is subjected to chemical filtration by allowing it to pass through a layer of carbon. This will absorb the odor and chemicals such as ammonia and chlorine from the water. Biological filtration is the last step. Here, a mixture of bacteria is allowed to act on the nitrites that are in the water. These toxic chemicals are converted into nitrates, which are less toxic.

Guide to proper choice of canister filters

1. Replacement parts are readily available

After some time of use, you will have to replace some of the parts of your aquarium filter. You have to do this as soon as you detect a problem in order to prevent leaks that might threaten the lives of the fish and other animals in your aquarium. It is best if the store where you will get the filter also offers the replacement parts. Get some spare rubber gaskets and impellers and store them near your aquarium.

2. Are these the right ones for your aquarium type?

While there are canister filters that will work for both freshwater and saltwater, there are some that are not recommended for saltwater. Inform the seller what type of aquarium you have before buying one.

3. Are these easy to use?

While you can get someone to install the canister filter for you, it should be easy enough for you to operate without any help from an expert. Also, you have to make sure that during emergencies, you will be able to manipulate the filters to prevent any danger on your pets. Many hobbyists prefer getting canister filters because they are inexpensive and have a variety of functions. With sufficient information on how to use them, your aquatic pets will have a better aquarium environment.

Anyone can easily set up a fish aquarium for a hobby or for decorative purposes nowadays. Fish supplies like fluorescent lighting and aquarium gravel are easily available, with many fish tank suppliers setting up shops on the Internet. As much as starting your own fish aquarium at home or in the office is simple, you need to make sure that you get the best fish tank supplies available.

Nonetheless, you might want to consider other types of fish tank water filters if you have a large fish tank. Most under gravel filters provide restricted water follow and movement and may not cover the entire length of a huge tank. Also, if you use sand for your aquarium, it is better to choose power or canister filters. Under gravel filters also create a lot of noise unlike most canister filters.

Filters which are typically placed at back of fish tanks are called power filters. What makes power filters beneficial is that they can work for any size of fish tank. It is also possible to use other types of filtration systems along with a power filter. Nonetheless, power filters are more ideal for fish tanks with gravel, rather than those which make use of sand.

Fish food plays a crucial role in keeping your fish in the best state of health. This is one of the most essential fish supplies. Different types of fish have different feeding requirements. The four basic types of fish food are flakes, pellets and tablets, live or fresh, and frozen or freeze-dried. Flakes fish food is ideal for surface feeders and bottom feeders, while live food like earthworms is more ideal for big-sized fishes.

Water pumps are valuable in maintaining oxygen levels inside the aquarium. Water filters keep the water clean from harmful impurities. Choosing the right pumps and filters will largely depend on the size of your fish tank. Illumination for the fish aquarium is important both for the fishes and for the live plants.

Lighting is especially important if live aquatic plants are used in your aquarium. You also need plant care supplies, to keep the live aquatic plants inside your tank healthy. However you should choose products that do not pose any health risks for your fishes. By using aquarium plant food and supplements, your aquarium will have a more natural look, creating an ideal place for your fishes.

Using the right gravel and sand substrates will assure the best condition of your fishes as well as the aquarium plants. These also provide better visual impact for your fish tank. From gravel and sand to colorful gems and gels, the choices are endless.

Filters are highly crucial for your fish tank, and they should be chosen with great care. Filters keep the water clean and provide the right level of aeration. In order to keep ammonia from accelerating to dangerously high levels, tank filters should be kept in place. Choosing the right fish tank water filters is one important task you should accomplish when setting up an aquarium.

Aquarium filters play an extremely important role in maintaining a proper environment in your fish tank. They remove toxins and chemicals from the water.

There are three types of filtration that a proper filter will provide, and all are necessary to keep your tank and the fish healthy. The types are chemical, mechanical, and biological filtration. Most filters that are on the market today will perform all three types of filtration. As far as the actual types of filters, there are several different types and styles. There are biowheel filters, internal, sponge filters, diatom, and wet/dry filters.

Aquarium filters also come as canister filters, undergravel filters, and power filters. Undergravel filters have somewhat of a bad reputation for not working very well. However, if you use them with a powerhead performance of the undergravel filter will be improved. Choosing the appropriate filter for you aquarium is very important. Choosing the wrong one can lead to an unhealthy. If you have too small of a filter chemicals and toxins that need to be removed will not be removed as well as they should. This will leave you with a tank that as an improper environment which in turn could lead to dead fish.

An aquarium filter provides a place for two bacteria types to grow which will establish a healthy biological filter. These bacteria are important for their ability to break down the chemicals that fish produce through their waste. Fish waste produces a chemical called ammonia, which is very toxic to fish, these bacteria break down this toxin into nitrites. Nitrites are also very toxic to fish, another bacteria breaks down nitrites into a less toxic chemical called nitrates. Aquarium filters reduce harmful toxins and can help maintain excellent water in aquariums, but it's still essential to clean your aquarium and to change some of the water twice each week.

Slime growth and stressed out fish are a result of improper filtration. Aquarium filters also assist in less algae build up in tanks. Doing your research on the proper size and kind of filter that you will need will help to ensure the health of your tank as well as your fish. With the right type of tank filtration your fish should live a long happy life.
