BOYU SF Sponge Internal Filters – Biological Aquarium Filters

The BOYU SF Sponge Internal Filter is an effective aquarium filtration solution designed to provide mechanical and biological filtration while supporting oxygen circulation in your aquarium. Featuring a high-quality bio-foam sponge, this filter helps trap suspended waste particles while providing a large surface area for beneficial bacteria to colonise.

Beneficial bacteria play an important role in biological filtration by helping break down harmful ammonia and nitrite produced by fish waste and uneaten food. This makes the BOYU SF Sponge Filter a suitable choice for freshwater aquariums, fish breeding tanks, fry-rearing tanks, shrimp aquariums, and setups housing sensitive fish species.

Powered by an external air pump, the sponge filter creates a gentle water flow while producing bubbles that help improve surface agitation and gas exchange. Its gentle filtration action makes it particularly useful for aquariums containing small fish, baby fish, shrimp, and other aquatic species that may be affected by strong water currents.

The BOYU SF series is available in five different models, allowing aquarium hobbyists to select a suitable sponge filter according to their tank requirements.

Key Features of BOYU SF Sponge Internal Filters

Efficient Biological Filtration

The bio-foam sponge provides a suitable surface for beneficial bacteria to establish and grow. These bacteria support the aquarium’s biological filtration process by converting toxic ammonia into nitrite and subsequently nitrate.

Mechanical Filtration

The sponge captures suspended particles, uneaten food, and other debris from aquarium water, helping maintain cleaner water.

Gentle Water Circulation

Air-powered operation creates gentle water movement without producing the strong currents commonly associated with some power filters. This makes it suitable for fry tanks, shrimp aquariums, and breeding setups.

Oxygenation and Surface Agitation

Rising air bubbles help circulate aquarium water and increase surface agitation, supporting gas exchange and oxygen availability.

Low-Maintenance Design

The reusable sponge can be cleaned easily during routine aquarium maintenance. Regular cleaning helps maintain water flow and filtration performance.

Pre-Filtration for Other Filters

The BOYU SF Sponge Filter can also be used as a supplementary pre-filter in compatible external or top-filter systems, helping capture larger debris before water reaches the main filtration unit.

How to Install the BOYU SF Sponge Internal Filters

Follow these simple steps to install your BOYU sponge filter correctly.

1. Connect the Adaptors: Insert the supplied adaptors at both ends of the connecting tubes.
2. Assemble the Filter: Connect the air tube to the filter body securely.
3. Position the Filter: Place the sponge filter inside the aquarium and ensure the sponge is fully submerged.
4. Remove Trapped Air: Gently squeeze the sponge underwater to release trapped air bubbles.
5. Connect an Air Pump: Attach the airline tubing to the air pump and connect it to the filter’s air inlet.
6. Adjust Airflow: Switch on the air pump and adjust the airflow according to your aquarium requirements.

An appropriate aquarium air pump is required for operation.

Cleaning and Maintenance Instructions

Proper maintenance helps preserve the filtration efficiency of your BOYU sponge filter and supports beneficial bacterial colonies.

• Clean the sponge when water flow becomes noticeably reduced.
• Remove the sponge and gently squeeze it in aquarium water removed during a water change.
• Avoid washing the sponge with untreated tap water, hot water, or chemical cleaning agents, as these may damage beneficial bacteria.
• Do not clean all established biological filter media simultaneously.
• Replace the sponge only when it becomes damaged or deteriorates significantly. Regular replacement is not always necessary.

Important: A newly installed sponge filter requires time to develop a mature beneficial bacterial colony. Do not rely on a new sponge filter as the only biological filtration source in an established aquarium until it has been properly cycled.
