How Reef-Spec Carbon (500G) Supports a Healthy System

Optimized for Reactors and Carbon Media Systems

Reef-Spec Carbon works efficiently in Reactors and Carbon (GFO) setups, ensuring consistent water contact for maximum absorption. This approach prevents organics from lingering and disrupting your aquarium’s balance.

Effective Organic Removal

Organic waste in reef aquariums can quickly break down into compounds that discolor water and create unpleasant smells. Reef-Spec captures these compounds before they degrade, improving visibility and keeping the system’s oxygen demand balanced.

Media Bag or Reactor: Choosing Your Method

• Reactor Use – Provides constant water flow through the carbon, increasing efficiency and lifespan.

• Media Bag Use – Works for smaller systems or where reactors are impractical. For best results, place in high-flow zones and knead weekly.

Usage Recommendations for Reef-Spec Carbon (500G)

• General Water Polishing – 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, positioned at the ozone reactor or skimmer outlet.

Key Tips for Maximum Efficiency

• Rinse carbon until water runs clear before use.

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

• Replace every 1.5–2 months for consistent results.
