Internal Aquarium Filters
An internal aquarium filter provides tanks with both mechanical and biological filtration, keeping fish and plants healthy by converting harmful waste into less harmful substances. As well as trapping physical debris and providing a surface area for bacteria to grow, some internal filters also aerate the water. Looking to keep your aquarium healthy?

Are internal filters good for fish tanks?
Internal filters are good for small fish tanks as they are compact and easy to install. They are also easy to clean and maintain, and can help circulate water, making them a cost-effective and straightforward way to care for your aquarium.
Is it better to have an internal or external filter in a fish tank?
If you have a larger tank with lots of fish and plants, external filters are generally considered the best option, as they offer better filtration due to higher flow rates. If you’ve got a smaller tank, an internal filter should do the job, especially if the tank is lightly stocked.
What does the internal filter do in an aquarium?
As well as trapping physical debris and supporting biological filtration, internal filters help with water circulation and, in some cases, have an aeration device that helps to increase oxygen levels. This helps keep your tank healthy, providing a nurturing environment for your fish and plants.
Is an internal filter good for plants in an aquarium?
Internal filters are particularly well-suited to planted aquariums based in smaller tanks. Alongside offering good filtration and circulation, they are also space-saving and easy to install. For larger aquariums, external filters are the best thing to use, as they are more flexible when it comes to flow direction and filter media options.
