Acurel Filter Fiber is a 100% polyester loose fiber floss for use with all aquarium filters. By covering the filter carbon with this material, an even greater amount of loose particles will be removed from suspension to provide a healthier environment for your aquarium fish.
Directions: Cover the filter carbon with a generous amount of Acurel Filter Fiber. For best results, replace fiber and filter carbon when excessive aquarium debris accumulates and fiber appears dry.
