• Adjustable flow for your aquarium setup.
• Extendable intake tube and intake sponge.
• Accessible filter cartridge for routine care.

Before you choose SF-02

Check the tank rim, lid opening and space behind the aquarium before choosing a hang-on-back filter. Confirm the operating water level and electrical requirements in the supplied instructions. Tank volume alone does not confirm fit.

What is included

Filter body, extension tube, filter cartridge, intake sponge and intake tube. Aquarium, animals and decorative items are not included.

Setup and care

Follow the instructions supplied with your exact model for mounting, operating water level and priming. Check the electrical rating on the product label. Never run the filter dry. Disconnect electrical equipment before maintenance as directed by the manual.

Matching replacement media

Use replacements marked for SF-02. Shop Seaforia SF-02 replacement filter cartridges (4-piece pack). Do not assume other SF or ST models use the same cartridge.
