Internal Filters

Internal aquarium filters provide the biological and mechanical filtration that is necessary to give aquatic life a healthy environment and crystal clear water. To ensure optimal filtration, it’s important to match your internal filter to your tank size. Internal fish tank filters and under gravel filters are suitable for small to medium tanks. For larger aquariums, an external filter will be required.
