Aquarium Co-Op Aquarium Filter Media Bag

• Easy to fill and empty
• Keeps loose filter media contained
• Less mess during filter maintenance

Keep your loose filter media better contained with a mesh filter media bag. They are great for bio rings, crushed coral, and carbon - among many other types (not recommended for Seachem Purigen). When it comes time to service your filter, pulling a bag of media out is much easier and less messy than trying to clean your filter with loose media inside. These bags are made of fine mesh so that water circulates freely around and throughout the media.
