A Guide to buying aquarium filters:

A filter should send all of the water in the tank through the filter at least four times each hour to properly maintain an aquarium. When selecting a system, consider the type of filtration it provides: biological, chemical, or mechanical. To variable degrees of effectiveness, several systems incorporate several types of filtrations. There are eight common types of filtration systems from which to choose.

Box Filters:

These were the first aquarium filters available for home aquariums, and were also known as corner filters or internal filters. Although they are less prevalent than in the previous, they are fairly affordable and may be filled with a variety of filter material. Many box filters are tiny devices that adhere to the glass of an aquarium, making them ideal for tiny aquariums of 20 gallons or less.

Corner filters are typically used in hospital tanks to cure sick fish since owners do not want to spend a lot of money putting up a tank that will be used seldom. Because of their lower input flow, box filters are popular in breeding tanks with small fry. Some versions necessitate the use of an air pump and an air connection to generate the movement required to flow water through the filter. These devices generate air bubbles, which improve chemical and biological filtration. The cost of these systems ranges from $8 to $30.  

Canister Filters:

Canisters are strong mechanical aquarium filters that are best suited for medium- to large-sized tanks (those greater than 40 gallons). Because canister filters are located outside of the tank, they may be easily hidden under or underneath the aquarium stand. These massive devices offer excellent mechanical, chemical, and biological filtration.

Diatomic Filters:

Diatomic systems are tank filters that “polish” the water by eliminating extremely tiny particles. These are similar in concept to diatomaceous earth swimming pool filters, which work by forcing water through a layer of very small particles to clean the water.  

Fluidized Bed Filters:

Relatively new, these systems are exceptionally effective biological filters that employ sand or silica chips as the filter media. Water is pushed through these devices, which are suspended from the rear of an aquarium, and then down through a mound of sand or other media. The microscopic particles give enough of surface space for bacterial colonies to flourish.

Sponge filters:

The sponge filter is attached to a tube that runs from a power head or an air pump. Bacteria will develop and develop biological filtration when water is driven through it. Mechanical filtration is also provided by sponge filters, albeit these clogs fast if there is too much dirt. The sponge prevents young fry from being sucked into the pump, making them ideal for tanks with fry.

Things to consider while buying a filter for aquarium:

  • Working: Most filters function mechanically by holding solid wastes until they can be manually removed later, and biologically by converting poisons in fish wastes to less dangerous nitrates that can be removed during water changes. Importantly, all filters require time to start operating, so they won’t be able to remove pollution right away — you’ll have to wait for them to develop.
  • Mature a new filter: We recommend utilizing a product like Waterlife Biomature, which incorporates ammonia as a source of food for the bacteria, as opposed to the older “fishless cycle” method. After you’ve finished setting up your tank, add the Biomature and monitor the water using ammonia and nitrite test kits, as directed. Ammonia and nitrite concentrations will have skyrocketed and then plummeted after several weeks. The tank should be ready for the first fish when you apply a tiny dosage of Biomature and the ammonia or nitrite levels do not rise. It usually takes four to six weeks for this to happen. Your tank ought to be effective in eliminating the wastes created by your new fish after this maturation period.
  • Adding fish: Some individuals like to mature their tank by adding a few robust fish, such as Zebra danios, which supply a food supply for the bacteria through their excrement. Although this method works, it exposes the fish to contaminated water, which is not ideal. There’s also the possibility that you’ll be tempted to add additional fish before the tank is complete, which will simply add to the contamination.

A filter is a beneficial addition to any aquarium, but in a tiny, 10-gallon aquarium, it is the greatest method to guarantee that your tank care efforts are not in vain and that you have an additional mechanism to keep your tank water pure.

What are the many sorts of filters available?

Internal power filters, which include a small water pump on top of a narrow box housing a sponge, are the simplest and extensively available. These are located inside the aquarium. Budget tanks may also include under gravel filters or external power filters, while more complex ones may have external power filters.

What is the purpose of an internal filter?

An internal filter is placed in the aquarium’s back corner, with the output immediately below the water’s surface. Internal filters are included in certain tanks, such as those in the Juwel line. Water is pulled through a coarse sponge that catches dirt at the bottom of the filter. Bacteria flourish in the dirty and oxygen-rich water that passes through the sponge.
