Blue Pet XF-280 Aquarium Sponge Filter

The Blue Pet XF-280 is an air-driven sponge filter for aquariums up to 150L, delivering gentle biological and mechanical filtration that keeps water clear and oxygenated without a strong current. Its multi-layer biochemical sponge gives beneficial bacteria a large surface to colonise while trapping debris, and because it runs on an air pump it is silent, energy-saving and safe for fry, shrimp and betta. A dependable primary filter for small community and breeding tanks, or a back-up biological filter in larger setups.

Why choose the Blue Pet XF-280?

• Gentle, fry- and shrimp-safe flow with no intake risk to small livestock.
• Biological + mechanical filtration from a multi-layer biochemical sponge.
• Silent and energy-saving — air-driven, no motor inside the tank.
• Boosts oxygenation through surface agitation from rising bubbles.
• Works in fresh and salt water, easy to rinse and reuse.

Specifications

Which tanks is it best for?

The XF-280 suits aquariums up to 150L as a primary biological filter, and is ideal for breeding, fry, shrimp and betta tanks, or as a supplementary filter in larger community tanks. It needs an air pump and airline to run. For the bigger version see the Blue Pet XF-380 (up to 380L), and compare types in canister vs HOB vs sponge.

How to set it up

Connect airline from your air pump, place the filter in the tank, and let the bubbles lift water through the sponge. Keep it running 24/7 so the bacteria survive, and rinse the sponge in old tank water (never tap water) when flow slows. See how aquarium filters work.
