Marineland Bio-Wheel Emperor Power Filters cartridges are designed for optimal performance and incredible ease of use. Rite-Size E cartridges feature Marineland's Black Diamond Premium Activated Carbon for excellent mechanical and chemical filtration.
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.
