## Summary description

AquaNatura TN-45200 sponge aquarium filter with bio-ceramic filtration media. Mechanical and biological filtration in one unit: porous sponge traps debris while bio-ceramic media supports beneficial nitrifying bacteria. Designed for gentle circulation in freshwater tanks; suitable for fry tanks, shrimp tanks, and quarantine setups. Supplied without an air pump — requires external air source or compatible lift tube setup.

## Long description

The AquaNatura TN-45200 sponge filter with bio-ceramic media combines mechanical and biological filtration in a compact unit designed for freshwater aquarium use. A porous sponge captures suspended debris while the included bio-ceramic media provides a large surface area for beneficial nitrifying bacteria to colonize. The design ensures gentle water movement suitable for delicate inhabitants such as fry and shrimp. The unit is supplied without an air pump and requires an external air source or compatible lift-tube connection for operation.
Advantages
The AquaNatura TN-45200 delivers both particulate removal and biological nitrification in a single module, reducing the need for multiple separate filters. Its sponge element is easy to remove and rinse for routine maintenance, while the bio-ceramic media sustains bacterial colonies that assist in ammonia and nitrite conversion. The gentle flow characteristics make it appropriate for tanks with low water current requirements. The compact footprint fits easily into small or quarantine setups.
Suitable for
 Fry rearing tanks where low flow and stable biological filtration are essential
 Shrimp and small invertebrate tanks that require gentle circulation and surface for biofilm growth
 Quarantine and hospital tanks where easy maintenance and reliable biofiltration are needed
 Small freshwater aquaria where space is limited and combined mechanical/biological filtration is preferred
When it may not be suitable
This sponge filter is not intended for large aquaria with high bioloads or systems that demand high flow rates and advanced multi-stage filtration. Because it is supplied without an air pump, buyers must provide a compatible air source or lift arrangement; without that, the filter will not operate. The unit is optimized for freshwater use and may not meet requirements for heavily planted or densely stocked tanks that require stronger circulation or additional nutrient control.
Key specifications
 Filtration type: Combined mechanical (sponge) and biological (bio-ceramic media)
 Media included: Porous sponge and bio-ceramic granules for bacterial colonization
 Flow characteristics: Gentle circulation suitable for low-current aquaria
 Intended water type: Freshwater
 Installation: Internal hang-on or submersible sponge filter requiring external airlift or pump connection
 Maintenance: Sponge is washable; bio-ceramic media retains beneficial bacteria when rinsed gently in tank water
How to use
Install the sponge filter submerged in the aquarium according to the tank layout and manufacturer guidance. Connect to a suitable external air pump using airline tubing and an air stone or lift tube as required to establish an upward flow through the sponge and media. Prime and check for consistent bubbling and water movement, adjusting air flow to achieve gentle circulation without stressing inhabitants. For maintenance, disconnect the air supply, remove the sponge and rinse it in tank water to avoid killing beneficial bacteria. Replace or top up bio-ceramic media as needed during deep cleaning, taking care to preserve some colonized media to accelerate biological recovery.
What to consider before purchase
 Requires an external air pump or compatible lift-tube setup; air pump not included
 Suitable primarily for small to medium freshwater tanks with low to moderate bioload
 Not a replacement for high-flow canister or power filters in large or heavily stocked systems
 Check tank dimensions and space to ensure the unit can be positioned without obstructing decor or equipment
Usage recommendations
For best results in fry and shrimp tanks, set air flow to produce gentle, steady movement through the sponge and avoid excessive turbulence. Perform regular sponge rinses in aquarium water and retain some colonized bio-ceramic media during maintenance to maintain biological stability.
