Filtration is a process of removing organic elements

Although experts don't agree at which pump works best for both aquariums and ponds, we certainly won't dip our fingers into that shouting match, because to be plain about it, choosing a filter is easy and simple. And one doesn't have to be an expert to know that. But first, what is filtration and when is it needed? Filtration is a process of removing organic elements that may pollute and thus affect the overall health of your aquarium. This is because of the presence of liquid and solid fish waste which when left alone could produce hazards for the fish and plants inside the aquarium. It is needed for the health of aquarium life, as earlier suggested, by bringing in a more stable environment, free of disease and pollution.

An unfiltered aquarium would usually cause unpleasant bacteria to grow and thrive in it. There are several types of filtration, depending on the "target" of the activity. A filler contains a material called media that has many functions. Some media would trap small particles of waste matter (mechanical filtration); some would provide a large surface which is colonized by a bacterium that consumes waste (bacteriological filtration); some would absorb or convert other toxins which cannot be trapped or converted by the first two media (Chemical filtration). But among the three, experts believe that bacteriological filtration still stands as the most significant in that it typically removes fish waste, which is dangerous to fish. If there are types of filtrations, there are also types of filters. And this is where the experts don't come into a consensus.

Most common of these are Internal Power Filters, External Power Filters, Air Pump driven or Powerhead driven Under-Gravel filters and Air Pump driven Internal Box Filters. The question now is how to choose. Basically, you have to identify the correct filter by assessing the usual problems in your aquarium. Second, know the volume of water that the filter is able to process. Third, choose a filter, which can turn over the entire aquarium volume between two to six times every hour with four times an hour. This simply means that its power can "clean up" the entire aquarium. Through this knowledge, you would know how to work out the water capacity of your aquarium for the filter to be more effective. There are many ways to know which filter is good for your aquarium. Still, to know which, you also have to know the needs of your fishes. Remember, learning how to choose your filter is only a step but it surely can go a long way.
