BOYU SF-104 Super Biochemical Sponge Aquarium Filter

The BOYU SF-104 Super Biochemical Sponge Filter is an aquarium filtration unit designed to provide mechanical and biological filtration while assisting with oxygenation of aquarium water.

The filter uses a structured sponge surface to trap suspended particles and provide a large surface area where beneficial bacteria can establish. It is designed to operate using an air pump and can also be used as an additional or pre-filtration unit in compatible aquarium filtration systems.

The SF-104 features a large cylindrical sponge body with a weighted base for stability inside the aquarium. Its sponge construction makes it suitable for aquarium environments where gentle filtration is preferred, including breeding and fry setups and aquariums containing sensitive aquatic species.

The unit does not have its own electric motor and requires a compatible air pump and airline connection for air-driven operation. Some product sources specify compatibility with standard aquarium air hose connections, while the product's listed inlet outer diameter is approximately 23 mm.

The sponge filter can be cleaned and maintained by rinsing the sponge appropriately during aquarium maintenance. Its simple construction makes it practical for ongoing aquarium filtration and biological media support.
