Internal Aquarium Filters
Aquarium internal filters are fully submersible filters that work inside your aquarium. They are great for smaller aquariums with low bioloads as they tend not to have large media chambers; in larger tanks they are useful as supplements to an external canister filter, as you can place them in "dead spots" in your tank to provide even flow through the whole aquarium and assist with the bioload. Internal filters are also a great choice for low water habitats like turtle tanks.
We carry a great selection of internal power filters; as well as low-tech, old school corner and box filter setups driven by air pumps and easily sufficient for small tanks with few fish. We also carry replacement filter cartridges and filter parts for most models.
