High-performance filtration for crystal-clear, contaminant-free water.
Waterbox Carbon Media is a premium-grade activated carbon designed to keep your aquarium water clean, clear, and free of impurities. Its highly porous, granular structure provides exceptional absorption capacity—removing organic waste, coral toxins, discoloration, odors, and residual medications that can accumulate over time.
By eliminating these unwanted compounds, Waterbox Carbon Media reduces stress on fish and corals while improving overall water quality and light penetration. Regular use helps maintain a stable, visually pristine environment for both freshwater and saltwater aquariums.
Key Benefits:
• Removes dissolved organics, odors, and water discoloration
• Eliminates coral toxins and residual medications
• Improves water clarity and light transmission for healthier corals
• Reduces stress and promotes livestock well-being
• Ideal for both freshwater and saltwater aquariums
For best results, use Waterbox Carbon Media as part of your regular filtration routine and replace the media monthly to maintain maximum effectiveness.
Directions for Use:
Use 100 ml of media per 100 L (25 gal) of aquarium water. Rinse thoroughly with RO/DI water before use. Replace media once per month or as needed based on water conditions.
