Filter wool 250g

Fine filter wool (250 g) – Crystal clear water for fresh and salt water

Ensure crystal-clear water in your aquarium! Our fine filter wool is the ultimate dirt trap for any filter system. The generous 250g pack provides a highly effective filter medium that reliably removes even the smallest particles from the water.

Why our filter wool is the right choice:

• Highest purity levels: The fine structure efficiently filters out even the smallest suspended particles, fish excrement and leftover food.
• Universally applicable: Whether internal filter, external filter or filter basin – the cotton wool can be individually cut to size and fits into any model.
• Suitable for fresh and saltwater: The fibers are completely neutral and do not release any pollutants into the water. Ideal for sensitive coral reefs or home planted aquariums.
• Stable and economical: The 250g pack is extremely fluffy and easy to portion without immediately collapsing in on itself.

Application tip:

Always place the fine filter wool as the third or fourth stage in your filter circuit (after the coarse sponges). This prevents clogging too quickly and maximizes the lifespan of your filter. Rinse briefly with lukewarm tap water before first use.

NOTE: For optimal water quality, we recommend replacing the filter floss regularly (every 1–3 weeks, depending on the level of contamination) instead of rinsing it. This will maintain full filter performance!
