## Long description

Aqua Nova NBF-300 is a replacement mechanical filtration sponge designed for aquarium canister, internal and modular filter cartridges. The sponge captures debris and suspended particulate matter, helping to maintain water clarity and reduce the frequency of clogging in downstream biological media. It is compatible with Aqua Nova filter accessories and intended for routine maintenance and filter performance restoration.
Advantages
The open-cell foam structure provides efficient capture of visible waste while allowing good water flow to downstream stages. As a mechanical filtration pad, it is washable and reusable for multiple maintenance cycles, reducing the need for frequent full cartridge replacements. The insert’s dimensions and flexibility enable it to fit inside various canister and internal filter housings where a compact mechanical layer is required.
Suitable for
Replacement mechanical pad in canister filters
Use inside internal and modular filter cartridges
Pre-filtration to protect biological media and pumps

Key specifications
Function: mechanical filtration by trapping debris and suspended particles
Material: open-cell foam (sponge) allowing water flow
Form factor: flat insert compatible with canister and internal filter cartridges
Maintenance: washable and reusable for several cleaning cycles
Compatibility: designed for use with Aqua Nova filter accessories and similar filter housings
How to use
Turn off the filter and remove the filter cartridge or open the filter housing according to the manufacturer’s instructions. Extract the existing mechanical pad and replace it with the Aqua Nova NBF-300 sponge insert, ensuring it sits securely and does not obstruct water pathways. After reassembly, restart the filter and check for proper flow. For cleaning, rinse the sponge in dechlorinated aquarium water or water taken from the aquarium to preserve beneficial bacteria; squeeze gently until the water runs clearer and allow to reposition in the filter.
Usage recommendations
Inspect the sponge during regular maintenance intervals and clean when visibly clogged. Replace the pad if damaged or if its structure no longer allows effective water flow. Use as a mechanical stage ahead of biological media to prolong the life and efficiency of downstream filtration components.
