The Three Types of Aquarium Filters
Aquarium filtration is essential for the health of fish and other aquatic life.
There are three main types of aquarium filters: mechanical, chemical, and biological.
Mechanical filters remove particles in the water by trapping them on a physical filter media, such as foam pads or floss, while chemical filters use activated carbon to absorb pollutants.
Biological filtration uses beneficial bacteria to break down ammonia and nitrites into less toxic nitrates.
Each type of filter works differently but all are necessary for an effective filtration system.
| Filtration Method | Mechanical Filtration | Chemical Filtration | Biological Filtration |
|---|---|---|---|
| Purpose | Removes solid particles from the water | Removes organic pollutants, toxins and odors | Breaks down waste and ammonia using beneficial bacteria |
| Equipment | Filter pad, filter sponge, filter floss | Activated carbon, zeolite, peat moss | Bio-balls, ceramic rings, gravel |
- Mechanical Filtration
Mechanical filtration is a process of removing particles from the water, allowing for a clean and healthy aquatic environment. It involves passing aquarium water through filter media that catches debris such as uneaten food, waste, and other particulates.
There are several types of mechanical filters available to aquarium owners including canister filters, internal filters, gravel filters, and filter pads. These all work by using tubes or hoses to draw water into the filter where it passes over or through different kinds of media such as carbon or filter pads before being pushed back out into the tank by an air pump or water pump.
The most important part of this type of filtration is its ability to remove biological waste from the water while still providing adequate flow rate throughout the system.
- Chemical Filtration
Chemical filtration is a process that utilizes chemical media to remove dissolved organic compounds from aquarium water, allowing for improved clarity and water quality. This process typically takes place in a filter chamber with an uplift tube, siphon tube, intake tube and lift tube.
Commonly used chemical additives for this type of filtration include bio pellets carbon, carbon insert, carbon traps and carbon units. A powerful pump is necessary to ensure proper circulation of the water within the filter chamber.
- Biological Filtration
Biological filtration is a process that utilizes beneficial bacteria to break down organic waste, resulting in improved water quality and clarity. It is an important part of aquarium filters, as it helps to remove chemical waste such as nitrogen compounds and toxic ammonia that can build-up from excess feedings or decaying organic material.
Biological filtration methods may include the use of biopellets, bio balls and other solid wastes which provide surface area for bacteria to colonize and consume nutrients. This process helps to convert toxic ammonia into less harmful nitrates, ultimately creating a healthier environment for aquatic life.
Which are the Most Popular Common Filter Types?
There are several types of filters commonly used in aquariums, including Canister Filters, Hang-on-Back Filters, Sponge Filters, Fluidized Bed Filters and Diatom Filters.
Of these, the most popular types of aquarium filters tend to be the Canister and Hang-on-Back models due to their efficient filtration capabilities and relatively straightforward installation process.
Sponge and Fluidized Bed filters are popular for aquarists with more specialized needs while Diatom Filters are best reserved for advanced hobbyists who require the utmost clarity from their tanks.
- Canister Filters
Possessing the advantage of a larger capacity, canister filters are among the most popular types of aquarium filtration systems.
This type of filter is installed outside the tank and typically contains multiple compartments filled with sponges, biopellets, carbon dosing media, and sometimes battery-operated air pumps for additional aeration.
What makes them unique is their ability to provide adjustable flow rates along with adequate water flow for maintaining an aquarium’s nitrogen cycle.
Canister filters use plastic balls or containers of balls in combination with fine mesh bags and trays in order to achieve specific filtration requirements for different types of aquariums.
- Hang-on-Back Filters
Hang-on-Back filters are a type of aquarium filtration system that is installed on the back wall of the tank, providing adjustable flow rates and efficient water circulation. They use various types of filter media to remove particles from the water and are usually powered by black pumps that provide enough pressure for the filter to operate.
Hang-on-Back filters also help to maintain a balanced nitrogen cycle in an aquarium, which is essential for keeping fish healthy as it prevents a high concentration of ammonia in the water. Additionally, these filters can be used with other types of filtration systems such as undergravel or canister filters to create more efficient filtration.
With their ease of installation and ability to effectively clean water, Hang-on-Back filters are an ideal choice for aquarists looking for optimal tank filtration.
- Sponge Filters
Sponge filters are a popular choice for fish tank filtration. These are indeed an effective and low-maintenance type of aquarium filter. Sponge filters consist of a plastic or ceramic tube with a sponge attached to the end. Water is drawn through the sponge, trapping debris and other particles in the process.
The trapped particles are then removed from the water by mechanical means such as vacuuming or siphoning.
- Fluidized Bed Filters
Fluidized bed filters are a type of aquarium filtration system that utilizes a bed of sand or gravel to trap debris and other particles. It is estimated that these filters can remove up to 99% of suspended solids from the water, making them an effective choice for maintaining clean and healthy aquariums.
The filter works by creating a fluidized bed in which the sand or gravel is suspended in the water column, allowing it to capture particles as they pass through. This process also helps to oxygenate the water, providing beneficial bacteria with an ideal environment for growth.
Additionally, fluidized bed filters require minimal maintenance and are relatively inexpensive compared to other types of filtration systems. As such, they are often recommended for hobbyists who want an efficient yet cost-effective way to keep their fish tanks clean and healthy.
- Diatom Filters
Diatomic filters are a type of filter that utilizes diatomaceous earth to remove particles from the water. This type of filter is often used in fish tanks, as it is effective at removing small particles and debris from the water.
Diatom filters work by passing water through a chamber filled with diatomaceous earth, which acts as a sieve to trap particles and debris. The filtered water then passes through another chamber where the trapped particles are removed.
Diatom filters are relatively inexpensive and easy to maintain, making them an ideal choice for aquarium owners who want to keep their tank clean without spending too much money or time on maintenance.
