The use of an aquarium filter will aid in your aquariums water quality and stability. Aquarium filters assist with three forms of filtration, biological, mechanical and chemical. Biological filtration occurs when beneficial bacteria convert ammonia into nitrites, and nitrites into nitrates. This process is called biological filtration because bacteria are required to complete this process, also called the nitrogen cycle. When starting a new aquarium, ammonia and nitrites build up before they are processed by beneficial bacteria—sometimes called New Tank Syndrome. Mechanical filtration occurs when waste and debris suspended in the water are removed by passing them over materials that capture small particles—such as synthetic foam or nylon fiber floss. The mechanical filter can also serve as a home for beneficial bacteria, making it the medium for the aquarium's biological filtration as well. And finally chemical filtration is the removal of dissolved substances from the water using media such as carbon. Show More SEO FAQs About Betta Fish Tank Filters Does my Betta tank need a filter?

The use of an aquarium filter will aid in your aquariums water quality and stability. Aquarium filters assist with three forms of filtration, biological, mechanical and chemical. Biological filtration occurs when beneficial bacteria convert ammonia into nitrites, and nitrites into nitrates. This process is called biological filtration because bacteria are required to complete this process, also called the nitrogen cycle. When starting a new aquarium, ammonia and nitrites build up before they are processed by beneficial bacteria—sometimes called New Tank Syndrome. Mechanical filtration occurs when waste and debris suspended in the water are removed by passing them over materials that capture small particles—such as synthetic foam or nylon fiber floss. The mechanical filter can also serve as a home for beneficial bacteria, making it the medium for the aquarium's biological filtration as well. And finally chemical filtration is the removal of dissolved substances from the water using media such as carbon. Show More SEO FAQs About Betta Fish Tank Filters Does my Betta tank need a filter?

The use of an aquarium filter will aid in your aquariums water quality and stability. Aquarium filters assist with three forms of filtration, biological, mechanical and chemical. Biological filtration occurs when beneficial bacteria convert ammonia into nitrites, and nitrites into nitrates. This process is called biological filtration because bacteria are required to complete this process, also called the nitrogen cycle. When starting a new aquarium, ammonia and nitrites build up before they are processed by beneficial bacteria—sometimes called New Tank Syndrome. Mechanical filtration occurs when waste and debris suspended in the water are removed by passing them over materials that capture small particles—such as synthetic foam or nylon fiber floss. The mechanical filter can also serve as a home for beneficial bacteria, making it the medium for the aquarium's biological filtration as well. And finally chemical filtration is the removal of dissolved substances from the water using media such as carbon. Show More SEO FAQs About Betta Fish Tank Filters Does my Betta tank need a filter?

The use of an aquarium filter will aid in your aquariums water quality and stability. Aquarium filters assist with three forms of filtration, biological, mechanical and chemical. Biological filtration occurs when beneficial bacteria convert ammonia into nitrites, and nitrites into nitrates. This process is called biological filtration because bacteria are required to complete this process, also called the nitrogen cycle. When starting a new aquarium, ammonia and nitrites build up before they are processed by beneficial bacteria—sometimes called New Tank Syndrome. Mechanical filtration occurs when waste and debris suspended in the water are removed by passing them over materials that capture small particles—such as synthetic foam or nylon fiber floss. The mechanical filter can also serve as a home for beneficial bacteria, making it the medium for the aquarium's biological filtration as well. And finally chemical filtration is the removal of dissolved substances from the water using media such as carbon. Show More SEO FAQs About Betta Fish Tank Filters Does my Betta tank need a filter?

The use of an aquarium filter will aid in your aquariums water quality and stability. Aquarium filters assist with three forms of filtration, biological, mechanical and chemical. Biological filtration occurs when beneficial bacteria convert ammonia into nitrites, and nitrites into nitrates. This process is called biological filtration because bacteria are required to complete this process, also called the nitrogen cycle. When starting a new aquarium, ammonia and nitrites build up before they are processed by beneficial bacteria—sometimes called New Tank Syndrome. Mechanical filtration occurs when waste and debris suspended in the water are removed by passing them over materials that capture small particles—such as synthetic foam or nylon fiber floss. The mechanical filter can also serve as a home for beneficial bacteria, making it the medium for the aquarium's biological filtration as well. And finally chemical filtration is the removal of dissolved substances from the water using media such as carbon. Show More SEO FAQs About Betta Fish Tank Filters Does my Betta tank need a filter?
