What is a filter cartridge / external filter?
A filter cartridge / external filter (let's call them boats for clarity) is usually a drum or container plastic with a motor on top of it. It is usually full of various media through plastic baskets and sucks the water, usually contains an excess of nutrients from the aquarium through a hose in the drum or container where water is forced through various media (see later in the article) and returned to the aquarium after being cleaned, through the engine at the top. There are several types, generally is a closed system and a wide range is available in all aquarium shops. It would be typical Eheim, Fluval, Tetra, and many others are also available.

What advantages are there, if any, in using one?
There are 4 advantages of using a cartridge filter in aquariums in my personal experience:
(1) for filtering biological
(2) for mechanical filtration
(3) for chemical filtration
(4) for additional water and stability of

Biological filtration
For disposal of waste water system and its conversion from ammonia to nitrogen gas through a colony of bacteria. This is the basis of the nitrogen cycle and an important filtering system. Life in the aquarium which is usually not exist without this filtering.

Mechanical filtration
For disposal of waste from large particles in the aquarium in general, using sponges or brushes, in some cases, then biological filtration can be much more efficient with smaller particles of debris.

Chemical filtration
To eliminate of drugs, organic waste and toxins from the water stream.

The additional water
This is usually an advantage for smaller aquariums, such as cubes of Nano and systems of less than 20 gallons if sink less. This also has the advantage of stable temperature and salinity due to excess water in the container. The pack also adds flow to the aquarium and when clean water is returned to the reservoir through the motor that moves the water.

What disadvantages there using one?
Well, more experienced aquarists have found that the filter cartridges can become dirty. This can, and usually ultimately lead the addition of nitrate boat to the system. Basically, fish waste and other debris as well as uneaten food or dead bodies trapped in the phase mechanical filter cartridge and due to bacteria in the biological filter does not get the opportunity to get to it, the waste is not converted by bacteria in harmless nitrogen gas. Usually waste is trapped in sponges or falls to the bottom of the can and it becomes a serious problem if left unattended. However, cleaning regularly, this can be avoided.

What media is available?
There are various media available to would not be able to list them all, however, some examples would be:

Biological filtration
Ceramic rings, bio balls, live rock or other type of stone rubble.

Mechanical filtration
Sponges or brushes.

Chemical filtration
Carbon Rowaphos or Phosban, and many other similar type that can remove chemicals from the water stream.

Is there any point using a boat with the media, little or nothing in it?
Yes there is, I think in the reef aquarium a bottle can be very useful for use with carbon and phosphate from media, as well as mentioned above, is useful for the additional volume of water in the aquarium and smaller water systems.

What size is not necessary?

There are various sizes of filter cartridges available with different flow rates and manufacturers to list their models preferred aquarium sizes in particular.
However, I do not think is accurate for estimating or suggest a certain size, since everything depends on what media is being used in the container and what is going to use the carbon filter. As you have discovered can be used in various ways so that the size will depend on the intended use

How often should be cleaned?
Again, this depends on its use in the particular system. If a boat is to be used for aquariums reef, then I suggest a week, if you use mechanical filtration, chemical filtration monthly if you use and every 2-3 months or longer if biological filtration is used. As you can see here is where the problem begins and why more experienced aquarists dislike and suggest not using them. If all 3 types of media will be used after the container is closed down every week and become a pain as the media would have to be removed to reach the sponges to clean them not possible and also senseless. With my experience with the cans that are about 25 years in all types of aquariums I suggest that they are useful for filtration products to add chemicals and water volume for smaller systems. I currently have a 92 gallon corner tank with a 13.5 gallon sump and not using a filter cartridge at the time of this system, but doing so in the future if he felt he needed one for my individual needs.

Well, what We have learned from this article. Basically a filter cartridge that can be useful and beneficial to smaller aquariums and tanks to hospital to remove the drugs from them and sump-less systems, due to the volume of water added, but have also learned that in general can be a nuisance to most reefs due to the constant cleaning and closing down to change and clean the media. We also learned that there are so many different types available means that, in general to the particular fan, whether it is practical and useful website usual gossip, rumors and jumping in the car has some merit, but it is not always the case. Depends on you if you use one, and only you will know if it is a useful tool or an obstacle to their reef aquarium.
