Red Sea Reef-Spec Carbon 250 G

Red Sea Reef-Spec Carbon (250 G) - Keep your Water Crystal Clear

Red Sea Reef-Spec Carbon (250 G) from Red Sea delivers powerful filtration for marine and reef aquariums. Designed for high-efficiency removal, it traps organics and odors fast, helping your system in Filtration & Skimmers stay balanced and healthy. With its specialized micro and macro pore structure, it clears yellowing compounds while maintaining stable water chemistry.

Why Reef-Spec Carbon (250 G) Makes a Difference

This carbon helps to remove pollutants before they can disrupt the balance of your reef. In reef aquarium systems, organic waste can break down quickly, which leads to discoloration, stress on your livestock, and unpleasant smells. By using premium carbon in your Filtration Reactor System, you can protect your water quality and limit unwanted microorganism growth.

Choosing Between a Media Bag and Reactor for Carbon

Reef-Spec Works Best in an Upflow Reactor

Reactors provide consistent water contact, increasing efficiency and control. Carbon in reactors remains active longer and produces cleaner results.

Using a Media Bag for Reef-Spec Carbon

A media bag still works well in smaller systems or where reactors aren’t possible. Place the bag in high-flow areas like sump baffles or overflow chambers. For best performance, knead the bag weekly so fresh carbon surfaces face the water.

Usage Guide for Reef-Spec Carbon (250 G)

• Organic load and tint removal – Use 50g per 50 gallons for 1–2 months.

• Post-medication cleanup – Use 100g per 50 gallons for 1 week.

• Ozone removal – Use 50g per 50mg/hr ozone output, placed at the reactor or skimmer outlet.

Tips for Maximizing Reef-Spec Carbon Efficiency

• Rinse carbon under tap water until the water runs clear.

• Maintain a flow rate of 250–400 GPH per 50 g.

• Replace every 1.5–2 months for consistent results.
