Sera Filter Wool[Weight - 100g]

Here's a rearranged and more polished version of the description:

Sera Filter Wool – Mechanical Prefiltration

Sera filter wool is designed for the mechanical prefiltration of fine dirt particles in aquarium filters. Made from durable, stable fibers, it effectively traps fine debris for extended periods without sticking together or collapsing. The filter wool can be rinsed and reused several times, making it a practical and long-lasting filtration medium. It is suitable for use in all types of filters.

For optimal biological filtration, we recommend Sera Siporax Professional. Its open-pored, three-dimensional structure provides a large surface area for beneficial bacteria, ensuring efficient and long-term pollutant breakdown.

Before first use, rinse all Sera filter media thoroughly under warm water.
