Mechanical Filtration

Mechanical filtration is the process of trapping and removing particles from a fluid using a filter. The filter can be anything from a sponge to a metal screen. The most common type of mechanical filtration is using a water filter. Betta fish are small tropical fish that can get use of a mechanical filter to keep them healthy. This is because their small internal organs do not produce enough waste to handle on their own. A mechanical filter removes debris and pollutants from the water, keeping your betta healthy and happy.

Chemical Filtration

Chemical filtration is the process used to remove unwanted chemicals and biological debris from the water. This can be done by using chemical or filter media in conjunction with beneficial bacteria, but other mechanical mediums may also be utilized for these processes. The most common type of chemical filtration is activated carbon filtration, which uses a material called activated carbon to absorb toxins and chemicals.

Biological Filtration

Biological filtration is the use of bacteria to remove unwanted waste in the water. Many people choose to add beneficial bacteria and nitrifying organisms into their aquariums, which can help with water quality and carbonate build-up. Bacteria can utilize nitrogenous compounds as energy sources, breaking down toxic materials that compete against healthy ones for nutrition within your tank so they do not have room to flourish or reproduce.

What Are the Different Types of Filters for Bettas?

Power Filter

A power filter works by trapping particles and debris as they are drawn through the filter. The larger particles are caught first, and then the finer particles are caught. This type of filter is typically used in aquariums with fish that require a high level of cleanliness, such as betta fish.

Internal Filter

Internal filters work by trapping and removing debris and particles from the water as it passes through the filter. They are typically made of a material such as sponge, foam, or cloth that can trap and remove large pieces of debris as well as smaller particles. This can help to improve the quality of the water and keep your betta fish healthy.

Undergravel Filter

Another type of filtration that can be used in aquariums with betta fish is an undergravel filter. Undergravel filters work by trapping swimming debris and particles as they pass through the gravel from the tank, which absorbs them into it for easy removal before creating a layer within your waterbed. This prevents harmful substances such as ammonia, nitrite, and phosphates from affecting your fish. For this reason alone you should look for an undergravel filter whenever choosing one for your aquarium.

Canister Filter

Canister filters work by trapping particles and debris that are small enough to pass through the filter’s pores. These filters are typically made of paper, plastic, or cloth and are placed in the aquarium. Betta fish do not require a filter, but they can benefit from one if it is properly installed and maintained.

Hang-on-Back Filter

Hang-on-back filters work by using a large net to trap the fish and then a smaller net to trap the filter media. The large net is held in place by a weight at the front and the smaller net is held in place by a weight at the back. When the fish swim through the large net they knock over the weight at the front which causes the large net to fall off the back of the tank and the smaller net to stay on. This allows the filter media to be trapped and cleaned.

Corner Filter

A corner filter is a type of filter that is specifically designed to work in corners or tight spaces. They are often made out of a more durable material than other types of filters, and they often have a wider mouth to allow for more debris to be caught.

A corner filter is a type of filter that is designed to be placed in the corner of a tank. The corner filter is designed to catch debris and small particles that are smaller than the filter’s mesh size.

Sponge Filters

Sponge filters work by trapping particles and bacteria that are small enough to go through the filter but large enough to be seen by the fish. This type of filter is very efficient in removing small particles and bacteria from the water, which is important for Bettas as they are known to have a sensitive digestive system.
