AC (Aqua Clean) Bio Filter Media is a high-porosity biological filtration medium designed for freshwater and marine aquariums, as well as sumps and pond systems.

Key Features & Benefits:

• High Surface Area: Features abundant nano and micro-pores (or specialized hexagonal/hollow structures like the Aqua Clean 3D variant reaching up to ~1850 m² per litre) that provide massive colonization space for beneficial nitrifying and denitrifying bacteria.
• Anaerobic Denitrification: A patented hollow or multi-level pore design creates hypoxic or anaerobic zones deep inside the media, allowing bacteria to convert nitrate into nitrogen gas for long-term nitrate management.
• pH Neutral & Safe: Maintains a neutral pH and General Hardness (GH), meaning it won’t drastically swing your water chemistry and is safe for sensitive fish and shrimp.
• Trace Element Release: Slowly dissolves trace elements to support the metabolism and overall health of aquarium inhabitants.
• Reusable: Washable and durable for long-term use in canister filters, sumps, trickle/shower filters, and hang-on-back (HOB) filters.

How to Use:

• Rinse Before Use: Always rinse the media thoroughly with old aquarium/tank water (never straight tap water, which can kill beneficial biology) to remove dust before placing it into your filter.
• Placement: Position it after your mechanical filtration (sponges or filter floss) so that the bio media only receives clean water free of heavy fish waste.
