## Summary description

Two-chamber sponge filter aqua nova NSF-120L (model 1435) designed for aquarium water filtration. Mechanical and biological filtration occur as water passes through sponge media in separate chambers. Suitable for freshwater setups, breeding tanks and shrimp or fry tanks where gentle filtration and surface agitation are required. Provides biological colonization surface and basic particulate removal.

## Long description

The sponge filter aqua nova NSF-120L two-chamber aquarium filter (model 1435) is designed to provide combined mechanical and biological filtration for small to medium freshwater aquariums. Water is drawn through two separate sponge chambers, which trap particulate matter and provide a surface for beneficial bacteria to colonize. The unit operates with low flow and minimal water movement, making it suitable for breeding setups, shrimp tanks and aquaria with delicate inhabitants that require gentle filtration and reduced current.
Advantages
The two-chamber design separates the mechanical and biological stages, improving particulate capture while maintaining effective biological filtration. Coarse and fine sponge layers extend maintenance intervals by retaining larger debris in the first chamber and allowing slower biological processes in the second. Low operational noise and low energy requirements make the filter easy to run continuously. The compact form factor fits easily into small tanks or dedicated breeding boxes without occupying significant space.
Suitable for
Freshwater community aquariums with small or delicate fish
Breeding and fry tanks where gentle water flow is required
Shrimp and invertebrate tanks that need biofilm and low shear filtration
Hospital or quarantine tanks for minimal water circulation
Key specifications
Filtration type: two-chamber sponge mechanical and biological filtration
Flow characteristics: low flow suitable for gentle currents
Media: sponge foam in dual chambers (coarse and fine porosity)
Installation: internal placement inside aquarium or breeding box
Maintenance: removable sponge elements for manual rinsing
Suitable water: freshwater aquaria
How to use
Install the sponge filter submerged at the side or corner of the aquarium and connect to an appropriate air pump or low-flow powerhead according to manufacturer recommendations. Prime the sponges by gently compressing them underwater to remove trapped air, then start the air supply. Monitor flow and adjust air or pump output to achieve the desired gentle circulation and surface agitation. Rinse the sponge media in dechlorinated water or tank water during routine maintenance to preserve beneficial bacteria and avoid full replacement unless necessary.
Usage recommendations
For optimal biological performance, avoid cleaning all sponge chambers at the same time; stagger rinsing to retain nitrifying bacteria. Use gentle rinsing in tank water and inspect sponge integrity regularly. Match air pump or powerhead output to the aquarium size to prevent excessive current that could stress fry or shrimp.
