The Seastainable Small Sponge Filter (3-Pack) provides highly efficient mechanical and biological filtration for nano aquariums, breeding setups, shrimp colonies, and quarantine tanks. Driven by a simple air pump, these internal filters draw water through a fine, high-density foam sponge that effectively traps floating particles while providing a massive surface area for beneficial nitrifying bacteria. The gentle, air-driven water flow generates excellent surface agitation and oxygen exchange without creating strong, turbulent currents, making it completely safe for delicate fry, baby shrimp, and slow-moving fish like Bettas. Sold in a convenient multi-pack, these reusable filters are easy to clean and maintain, providing an ideal filtration baseline for multi-tank fish rooms.
Key benefits:
Gentle Air-Driven Current: Provides steady water movement and oxygenation without strong currents, ensuring baby shrimp and fry never get trapped or sucked in.
Excellent Biological Filtration: The high-density sponge structure establishes a massive colonization zone for beneficial bacteria to process ammonia and nitrite.
Economical 3-Pack Bundle: Comes with three matching small sponge filters, making it easy to outfit quarantine setups, hospital tanks, or multiple breeding bins.
Heavy Weighted Base: Designed with a sturdy base plate that keeps the filter resting securely on the bottom of the tank without floating.
Specifications:
Size: Small
Quantity: 3 Filters per pack
Filter Type: Air-driven internal sponge filter
Required Accessories: Requires an external air pump, airline tubing, and a check valve (sold separately)
Water type: Freshwater and Saltwater
Intended users: Shrimp breeders, fish breeders, Betta keepers, and aquarists running quarantine tanks
Suggested use:
Installation: Attach standard 1/4" airline tubing from your air pump to the intake tube of the sponge filter. Submerge the filter in your aquarium and squeeze the sponge several times underwater to release trapped air so the unit sinks to the bottom.
Maintenance: Rinse and squeeze the sponge inside a container of pulled aquarium water during regular water changes. Never rinse the sponge in tap water, as chlorine will instantly destroy the beneficial bacteria colony.
Storage and safety:
Store dry filters in a clean place when not in use.
Warnings:
Always utilize a check valve in your airline tubing setup to prevent water from back-siphoning into your air pump if the power goes out.
Keep out of reach of children.
What’s included:
3 x Seastainable Small Sponge Filters
Why choose:
Standard power filters are often too strong for fragile livestock like fry or shrimp. The Seastainable Small Sponge Filter 3-Pack offers a safe, gentle, and reliable biological filtration setup that keeps your most delicate inhabitants safe while giving you three complete units for your multi-tank projects.
