Coarse filter wool for mechanical cleaning of the water

Mechanical cleaning of the water is crucial for a clear view of the aquarium and the basis for reliable biological conditioning. With the Filter Wool Coarse, coarse dirt particles such as waste of the animals, food and plant remainders are filtered out of the water. The filter wool is ideal for use as the last step of mechanical cleaning. The following biological filter media are thus optimally protected from pollution and can work reliably, so that the service life of the filter is prolonged.
Rinse with warm water before use. Add the required amount of filter wool to the filter. Can be washed several times. Replace in case of strong pollution.
