## Summary description

Replacement filter foam pad designed for pre-filtering in Tetra EX500, EX700 and EX1000 aquarium filters. This sponge provides mechanical trapping of debris and protects main filter media and pump from large particles. Suited for routine maintenance and sponge swaps to maintain water clarity and extend service life of internal filter components.

## Long description

This replacement filter foam pad is designed for use as a pre-filter in Tetra EX500, EX700 and EX1000 internal aquarium filters. The sponge provides mechanical removal of larger debris, capturing uneaten food, plant fragments and suspended particles before they reach the main filter media and impeller. Intended for routine maintenance, the foam pad helps maintain water clarity and reduce the load on biological and chemical filter stages.
Advantages
The foam pad is cut to fit the pre-filter chamber of compatible Tetra EX series units, offering consistent mechanical filtration without altering flow rates significantly. It extends the service life of the main filter media and protects the pump from clogging by large particles. The open-cell structure allows easy rinsing and quick drying between changes, supporting regular maintenance cycles and predictable performance.
Suitable for
 Pre-filtering in Tetra EX500 internal aquarium filters
 Pre-filtering in Tetra EX700 internal aquarium filters
 Pre-filtering in Tetra EX1000 internal aquarium filters
 Routine maintenance and sponge replacement to reduce debris load
Key specifications
 Material: open-cell foam suitable for mechanical filtration
 Function: pre-filtration / mechanical debris trapping
 Compatibility: shaped to fit specified internal filter models’ pre-filter chamber
 Maintenance: washable and reusable with periodic replacement recommended
 Effect on flow: minimal restriction when properly fitted
How to use
Turn off and unplug the filter before removing the housing. Remove the old foam pad from the pre-filter compartment and inspect the surrounding media and impeller for accumulated debris. Rinse the replacement foam under aquarium water or dechlorinated tap water to remove dust and compress it gently to expel trapped air. Insert the foam pad into the pre-filter chamber with the correct orientation so it sits flush and does not obstruct impeller movement. Reassemble the filter, refill if required, and restart the unit. Inspect operation and flow after installation to confirm proper fit.
Usage recommendations
Rinse the foam pad during routine water changes using aquarium water to preserve beneficial bacteria. Replace the pad when it no longer springs back after squeezing, shows persistent staining, or causes noticeable flow reduction. Avoid using detergents or bleach when cleaning. For heavily soiled systems, perform more frequent inspections and cleaning to prevent reduced filtration performance.
