Fluidized Bed Filters
Fish tanks usually come with a filter at the back which holds on to the rear of the fish bowl. These sorts of filters use bacteria to produce extremely effective biological filtering. They're most suitable for small aquariums.
Sponge/air-driven Filters
Sponge filters function by using an airflow system to move water through a sponge that offers both organic and also mechanical filtration. These types of filters are most effective for small aquarium tanks.
Ease Of Cleaning
These filters are designed to be easily cleaned without losing their effectiveness.
As long as it works, use it. If not, don't worry too much about it.
Most high-quality products are designed so that they require cleaning to keep their performance up.
Always be sure that you can replace some of the filter media if you need to without having to replace all of it at once. If you do so, you may end up killing off some of the fish.

Canister Filters
A container filter provides excellent mechanical, biological, and chemical filtration for large fish tanks or those with lots of fish. It holds multiple different kinds of filter media within the canister for the finest water purity feasible.
Internal Power Filters
Inner power filtration uses extremely efficient filtration as well because it's placed at the back of the aquarium. It moves the water effectively since it's usually used in smaller tanks that are 20 gallons or less in size.
Wet/dry Filters
Wet/dry filters provide extremely effective organic filtration. The biological media is subjected to both wet and dry conditions, allowing a large number of beneficial microorganisms to flourish. These types of filters work best for a big aquarium.
Undergravel Filters
Undergravel filtration systems rest beneath a bed of gravel inside an aquarium and pull water through the gravel using the crushed stone to provide organic purifications. These types of filters function well for small or large fish tanks, but the fish must be light.
Types Of Aquarium Filtration
There are three basic types of aquarium filtration: mechanical, chemical, and biological.
- A mechanical aquarium filtration system uses some sort of filter material to drive the aquarium's water through.
- Chemical purification removes certain substances from the water by passing them through filters or resins.
- Organically grown plants require less fertilization than nonorganic ones. Fertilizing helps promote plant growth and prevent nutrient deficiency. However, too much fertilizer can cause toxicity issues.

Substrates And Plants
If you grow aquatic plant life in your tank, this can affect your water quality.
A heavily planted aquarium, especially one with soil and gravel as substrate, is able to process nitrogen effectively making anaerobic filters less important for heavily stocked aquariums and aquarists who don't perform regular water changes.
If you're not already doing so, you should add some sort of substrate to your aquariums to help keep them from becoming too acidic. A good option would be to use a soil mix made up of equal parts peat moss and perlite (or any type of medium) and then adding some gravel or shells to provide structure. You could even add some live rock if you want.

Power Filters
Filters are among the most common type of aquarium filtration system as well as can provide biological, physical, and also mechanical filtration. They typically hang on the rear side of the aquarium and need replaceable cartridges. This kind of filtration works well for most aquarium sizes.
FAQs
1. What Maintenance Does An Aquarium Filter Require?
Depending on which kind of filter you have, it may be necessary to replace it after a month. You should also take away the filter from the container, and then tidy everything up according to the manufacturer's guidelines. The right method to wash a filter differs depending on its kind, so ensure to follow the directions provided by your owner's manual.
2. Does Using An Aquarium Filter Mean I Don’t Have To Change The Water In My Fish Tank?
A filtration system helps keep the aquarium clean; however, you still need to perform routine partial-tank replacements to ensure good quality. In general, this means changing around 25 percent of the tank's volume with new, filtered tap or bottled drinking H2O.
3. What Type Of Filters Work Best For Large Or Extra-large Aquariums?
For larger aquarium sizes, container filters are an ideal option because they're large enough to handle a lot of water and filter efficiently. Dry/wet filters also perform well for large storage tank sizes of approximately 120 gallons.
