Aqua One Filter Air 85

Provide safe, gentle, and reliable biological filtration for medium-sized aquariums with the Aqua One Filter Air 85 Sponge Filter. Designed specifically for delicate aquatic life, fry rearing, and shrimp habitats, this internal sponge filter provides superior mechanical and biological filtration without risking harm to tiny or slow-swimming livestock.

The open-cell foam sponge provides an enlarged surface area for beneficial nitrifying bacteria to colonize, ensuring efficient breakdown of toxic ammonia and nitrites. Equipped with a heavy weighted base, the Filter Air 85 stays securely anchored at the bottom of the tank without shifting or floating. Simply connect to a standard air pump or small water pump head to create safe, oxygen-rich water movement.

Key Features & Benefits

• Safe & Gentle Suction: Gentle water movement prevents weak swimmers, newborn fry, and baby shrimp from getting trapped or sucked into the filter.

• Expanded Surface Area: Fine open-cell foam maximizes space for beneficial nitrifying bacteria to establish robust biological filtration.

• Heavy Weighted Base: Keeps the filter firmly positioned on the substrate or bare aquarium bottom without floating.

• Versatile Power Options: Easily powered using a standard aquarium air pump (with airline tubing) or connected to a small water pump head.

• Simple Maintenance: Easy to assemble, disassemble, and clean; simply rinse the sponge in siphoned aquarium water during routine maintenance.

Suitable For

• Freshwater Shrimp Aquariums (e.g., Cherry Shrimp, Crystal Red Shrimp)

• Breeding & Fry Rearing Tanks (e.g., Betta fry, Guppy fry, Cichlid wrigglers)

• Medium Freshwater Aquariums & Grow-Out Tanks (up to ~85L)

• Hospital, Quarantine, and Isolation Aquariums

Cleaning & Maintenance

To preserve the beneficial bacterial colony inhabiting the sponge, rinse and squeeze the foam element in a bucket of siphoned aquarium water during regular water changes. Never rinse the sponge under unchlorinated tap water or use hot water, as this will destroy the beneficial nitrifying bacteria.
