Rowa Carbon 1L is a high-performance activated carbon media designed to deliver crystal clear water in both freshwater and marine aquariums. Made from top-grade hard coal, it offers exceptional adsorption capacity while maintaining one of the lowest phosphate levels available on the market.

With its pelleted form and large surface area, Rowa Carbon effectively removes toxins, discolouration, and unwanted organic compounds, improving light penetration and supporting the overall health of fish, corals, and plants. Unlike lower-cost alternatives that may leach phosphate, Rowa Carbon has a Phosphate Output Index (POI) of just 1.3—well below the detection limit of most test kits—reducing the risk of algae outbreaks.

The 1L pack provides an efficient solution for advanced filtration and long-term aquarium clarity, with a pH-balanced formulation safe for sensitive aquatic systems.

Key Features:

• Ultra-low phosphate release – POI of just 1.3
• Removes yellowing, odours, and toxins from the water
• Supports healthy livestock and clearer light penetration
• Highly porous pelleted structure for superior adsorption
• pH balanced and safe for marine and freshwater tanks
• Free from phosphoric acid – unlike lower-grade carbons

Ideal for aquarists looking for a reliable and low-risk carbon media that offers strong performance without compromising water quality.
