Every aquarium owner is interested in his device working stably and efficiently, and the fish lived for a long time. An important role in achieving these goals is played by good water filtration. What is the best filter for the aquarium and what rules to consider when choosing it? Let’s try to figure it out.
Types and application
The choice of filter should be made taking into account who lives in the aquarium, what plants are in it and how many are there. If the aquarium is large, there are many plants and living creatures in it, then the filter should be powerful, effectively remove all contaminants from the water. To date, there are several types of filtration of water in an aquarium: mechanical; chemical; biological; combined. What are the best filters for an aquarium? Consider the main features of each filtering system. Mechanical Data filters are considered the simplest, but also the most effective for servicing aquariums of different sizes. Outwardly, they resemble a simple glass consisting of a pump (motor) and an absorbent sponge. The pump pumps the water in the aquarium, it passes through the sponge, as a result of which it is cleaned. Such filtering is effective for removing large contaminants – the uneaten food, fish excreta, residues of dead organisms. So if you are looking for which is the best filter for a small aquarium, give preference to mechanical models.
Thanks to chemical filters, water is treated through absorbents, most often aquarium coal is used for this purpose. It is advisable to use ion exchange resins, such as zeolite. Such filters are more efficient and practical due to the porosity of absorbent materials that absorb dirt particles well. Ion exchange resins do well with harmful poisons in the form of ammonia, nitrates and nitrites, which gradually accumulate in the aquarium. Biological The best and reliable filtering for an aquarium is based on a biological filter. This method of water purification implies the presence of a special compartment in the filter itself, which is necessary for the cultivation of beneficial bacteria. For their reproduction, a special substrate is used. Bacteria play an important role, as they saturate water with useful substances and decompose harmful substances: ammonia, nitrites and nitrates – to a gaseous state. They are the most serious and dangerous enemy for aquarium inhabitants, leading to diseases and the death of fish. If you still doubt which filter is better for the aquarium to choose, consider the biological options.
These filters are convenient because they can purify water in various ways. Moreover, even the simplest mechanical model can be used as a combination, for example, by combining an absorbent sponge with aquarium coal. So the conclusion can be drawn as follows. For a small aquarium, mechanical devices are the most profitable option: cheap, but simple and convenient to operate. If the aquarium is large, then you need to consult with a specialist who will help decide which filter is best for an aquarium of 100 liters and more. Most often it is recommended to use a biofilter, which, with a higher price and difficulty in cleaning, will be effective and durable. By the way, consider the filter’s throughput. The effectiveness of his work depends on it. Depending on the location of the Fish Tank Filters are divided into internal, external or mounted. Consider the features of each species in more detail.
