Important Considerations When Choosing Your Fish Tank Filter

One of the most crucial pieces of equipment in any aquarium are fish tank filters but it is also one where little consideration is initially given. It is this piece of equipment that maintains the delicate level of water purification in the aquarium by providing for an ecosystem that is able to sustain your aquatic life.



The aquarium is an enclosed ecosystem unlike the lakes and sea from which the fish originated from. In nature, the size of the body of water plus the conditions of nature balances off the chemical concentration and pH levels making it perfect for fish to live and breed. However in the fish tank, the amount of water is little and it is only the filter that helps in discarding waste matter and balancing acidic levels to sustainable conditions.



When buying a fish tank filter, there are a number of factors which you do need to consider before actually making the purchase. They include the price of the filter, the amount of maintenance you are able to do and the type of aquatic life that you are planning to keep.



Price is definitely a big consideration. There are so many fish tank filters to choose from and their costs can range from a few dollars to hundreds. Canister fish tank filters are without a doubt the most expensive and for the price that you pay, they do provide excellent filtration. The same goes for diatom fish tank filters. These costly filters also require very little maintenance and allow you to go for long periods of time without the need for a water change. The less costly filters such as corner filters or sponge filters will require a lot more maintenance and cleaning and do not supply as good filtration as their more expensive alternatives.



How much maintenance you are willing to perform for your aquarium will greater affect the type of fish tank filter that you buy. If you are a busy person with very little time on your hands, you will need to opt for filters that need little maintenance. These include canister filters and diatom filters. But these filters do come with a high price. If you are not willing to spend that amount on your aquarium, bear in mind that you will have to perform frequent maintenance. For undergravel filters, this includes vacuuming the gravel. For sponge filters, it would mean washing the sponge and for corner filters, you would need to remove the filter media from the box and wash it. Not doing this will cause the filter to be clogged and may even back the waste up into the aquarium water.



The type of fish you plan to keep in your aquarium is the final factor. The main concern here is the strength of the filter suction. If the suction is too strong, fish that are weak might get pulled in or stuck at the suction inlet. This will most likely kill your aquatic life. Canister, diatom and power filters tend to have too strong suction but the more expensive models might allow you to reduce this. I would suggest placing a small cage like attachment or a sponge head over the inlet to so that suction will not be focus on a small area. Undergravel and sponge filters are ideal for aquatic life that are weaker. The fish would be sucked in no matter how strong the suction is.



These are the most crucial factors that you will need to make when deciding to buy an aquarium filter. For more information on fish tank filters and other aquarium guides visit Fish Tank Filters at http://fish-tank-filters.org today.
