Sera Filter Wool suodatusvilla 100 g

Fine filter wool for the mechanical cleaning of the water, in a 100 gram pack. The range has four pack sizes: 100, 250, 500 and 1,000 g.

What it is for: fine filter wool takes the small particles out of the water – animal waste, food remains and plant debris. The manufacturer recommends it as the last stage of mechanical filtration, before the biological part.

Why the order matters: with the wool last, the biological media that follow stay clean and work reliably. That extends the service interval of the whole filter.

Material and use: residue-free synthetic fibre, Oeko-Tex certified. Rinse the wool in warm water before use; it can be washed several times. Replace it only once it is heavily soiled.
