Find a productProduct description
This two-piece set of sponge inserts is intended for aquarists running Aquael Versamax 1 filters. It replaces worn media in the filter chamber and covers two roles at once: capturing particles and supporting the bacteria that process waste in the tank.
Why it matters
- Phenol-free sponge: the inserts are made from carefully selected sponge material that is free of phenol.
- Mechanical filtration: the foam retains debris and suspended matter that is visible to the naked eye, keeping it out of the water column.
- Biological filtration: the porous structure provides a substrate for nitrifying bacteria, so the same insert also works as biological media.
- Maintenance method: the manufacturer specifies cleaning only in old water taken from the aquarium during a water change, which protects the bacterial colony.

What it works with
The inserts are designed for the Versamax 1 filter line and are suited to freshwater aquarium setups where sponge media is used for mechanical and biological filtration. Replace them on the schedule recommended by the manufacturer, and clean them only in water drawn from the tank during routine water changes so the nitrifying bacteria are not lost.

Frequently asked questions
The sponge is made from phenol-free foam, so it contains no phenol. It is made from carefully selected sponge material.
It provides mechanical filtration and traps debris and suspended particles that are visible to the naked eye. Smaller particles that you cannot see are not listed as being captured.
Yes, the foam serves as a surface for nitrifying bacteria, so it also performs biological filtration while catching debris. This means the insert does two jobs at once.
The manufacturer recommends rinsing it only in old water taken from the aquarium during a water change. Using old aquarium water helps preserve the bacteria living in the foam.
Each package contains two sponge inserts. You can use one set in your filter and keep a spare for replacement.
