Eheim – 2501101 – Activated Carbon – 2 L

Eheim Activated Carbon – 2 L

The Eheim 2501101 Activated Carbon is a premium filtration media designed for freshwater aquarium systems. Packaged in a convenient 2‑liter bag, it delivers superior adsorption of dissolved organic compounds, pharmaceuticals, and other contaminants that can compromise water quality and fish health.

Key Features

• High Surface Area: Each grain offers an extensive surface for chemical reactions, ensuring rapid removal of impurities.
• Pure, Non‑Toxic Composition: Made from natural wood sources, the carbon is free from additives and heavy metals.
• Long‑Lasting Effectiveness: Provides consistent performance over extended periods before saturation.
• Easy Integration: Fits seamlessly into most external filter housings or can be used in internal media baskets.

Primary Functions

The activated carbon works through adsorption, a process where molecules adhere to the surface of the carbon. This mechanism is particularly effective for:

• Removing Chlorine and Chloramine: Protects fish from harmful disinfectants often present in tap water.
• Eliminating Organic Toxins: Breaks down waste products such as ammonia breakdown byproducts, phenols, and other dissolved organics.
• Reducing Odors and Unpleasant Flavors: Enhances the overall sensory quality of the aquarium water.
• Neutralizing Pharmaceutical Residues: Helps mitigate trace amounts of medications that may enter the system through fish waste or uneaten food.

Installation Guidelines

1. Preparation: Rinse the carbon lightly with clean water to remove any dust or loose particles. Avoid soaking, as this can reduce adsorption capacity.
2. Placement: Insert the 2‑liter bag into a filter cartridge, media basket, or external filter chamber. Ensure it is fully submerged and not compressed by other media.
3. Flow Rate: Maintain a moderate water flow (approximately 1–3 L/min per liter of carbon) to allow sufficient contact time without causing excessive turbulence.
