Red Sea Reef Spec Carbon is a premium activated carbon formulated for marine and reef aquariums. It efficiently removes organic pollutants, discoloration, toxins, and odors, ensuring crystal-clear water and a healthy environment for sensitive corals and marine life. Its fast-acting nature, low phosphate content, and long-lasting performance make it an ideal choice for reef tanks, helping maintain pristine water conditions without encouraging unwanted algae growth.
High Adsorption Efficiency: Removes dissolved organic compounds (DOCs), harmful toxins, and other pollutants with advanced porous structure.
Fast-Acting: Quickly clears water discoloration and eliminates odors.
Phosphate-Free: Safe for sensitive reef environments, preventing algae growth.
Low Dust: Pre-washed to minimize dust and reduce initial water cloudiness.
Optimal Grain Size: Maximizes surface area and water flow for superior adsorption efficiency.
Rinse Before Use: Thoroughly rinse the carbon with freshwater to remove dust.
Placement: Use in a media bag or filter compartment; position in high-flow areas like canister filters, sumps, or reactors.
Maintenance: Replace every 1–2 months or when water discoloration or DOC levels increase. Heavily stocked tanks may require more frequent changes.
Maximize Efficiency: Ensure even water flow through the media to prevent clogging and ensure optimal adsorption.
200 ml: Treats up to 200 liters, lasts 1–2 months
500 ml: Treats up to 500 liters, lasts 1–2 months
1000 ml: Treats up to 1000 liters, lasts 1–2 months
2000 ml: Treats up to 2000 liters, lasts 1–2 months
For Clear Water: Ideal for maintaining crystal-clear water after water changes or when pollutants accumulate.
Perfect for Reef Systems: Essential for reef aquariums with sensitive corals requiring pristine water.
Regular Monitoring: Test water quality regularly and replace carbon as needed.
Complement with Other Filtration: Best used alongside mechanical, biological, and chemical filtration for a comprehensive approach.
Use Moderately: Avoid overuse to prevent stripping beneficial compounds needed by some corals.
