Premium Aquarium Sponge Filter (Single/Double Head) | Air-Driven Bio-Filter for Shrimp & Fish Fry | Air Pump Required

Premium Air-Driven Aquarium Sponge Filter

Achieve crystal clear water and massive oxygenation with our classic Air-Driven Sponge Filters from Atradesen.com. Highly recommended by professional shrimp breeders and fish keepers, this gentle yet highly effective bio-filter utilizes an eco-friendly ribbed sponge to trap floating debris while providing a massive surface area for beneficial bacteria to thrive.

🌟 Gentle Bio-Filtration & Aeration

• 100% Shrimp & Fry Safe: Unlike motorized power filters that can suck up delicate baby fish and dwarf shrimp, the gentle water intake of this sponge filter ensures your fragile livestock remains completely safe.
• Dual-Action Performance: As air bubbles rise through the clear exhaust tube, they draw dirty water through the sponge (mechanical filtration) and release it at the surface, creating massive surface agitation and oxygenation.
• Space-Saving Suction Mount: Mounts securely to the aquarium glass via the included heavy-duty suction cups. Available in Single and Double sponge configurations to fit tanks from 10cm up to 80cm.

🚨 Operation Guide & Warning (Crucial!)

This filter operates purely on air displacement physics. Please read the Atradesen.com operational rules before buying to avoid setup failures:

• ⚠️ AIR PUMP REQUIRED: This filter DOES NOT contain an electric water pump! You MUST connect it to an external aquarium Air Pump using standard 4mm airline tubing for it to work. (Air pump and tubing are SOLD SEPARATELY).
• Check Valve Recommended: Always install a one-way check valve on your airline tubing to prevent water from siphoning back into your air pump during a power outage.
