A pad of double-thick polyfiber mechanically filters out floating waste and debris before allowing water to pass and be chemically filtered through Marineland's Black Diamond Premium Activated Carbon. Rite-Size cartridges feature a patented ribbed backing to maintain their shape, ensuring even distribution of activated carbon for maximum water-to-carbon contact.

For best results, change cartridge every 2-4 weeks.
