Keep your aquarium water crystal clear with high-quality activated carbon, designed to remove dissolved organic waste, discoloration, odors, and unwanted impurities without affecting essential water chemistry.

Ideal for freshwater and marine aquariums, this carbon delivers fast, effective chemical filtration while remaining safe for fish, plants, and invertebrates.

Key Features

Removes yellowing, toxins, and odors

Helps maintain crystal clear water

High-porosity structure for maximum adsorption

Safe for freshwater and marine aquariums

Rinse-ready and easy to use

• Neutral to pH when used correctly
  

Ideal For

• Routine aquarium filtration
• Removing medications after treatment
• Clearing tannins from driftwood
• Improving water clarity and polish
• Freshwater, planted, and marine systems
  

How It Works

Activated carbon adsorbs:

• Dissolved organics
  
• Phenols and tannins
  
• Chemical residues
  
• Odors and discoloration
  

This results in visibly clearer water and a healthier aquarium environment.

Usage Instructions

1. Rinse carbon thoroughly under tap or RO water until clear
   
2. Place in a media bag or filter chamber
   
3. Position after mechanical filtration for best performance
   
4. Replace every 3–4 weeks depending on bioload
   

Compatibility

• Canister filters
  
• Hang-on-back filters
  
• Internal filters
  
• Sump systems (in media bags)
  

Safety Notes

• Remove carbon when dosing medications
  
• Do not reuse exhausted carbon
  
• Store unused carbon in a dry environment
  

Why Use Quality Carbon?

Not all carbon is equal. High-quality activated carbon offers:

• Faster adsorption
  
• Lower dust content
  
• Longer effective lifespan
  
• leaner, clearer results
  

A simple but essential upgrade for maintaining pristine aquarium water.

Q: What is Elixr Carbon used for?

A: Elixr Carbon is premium activated carbon filter media designed to remove dissolved organic waste, tannins, odours, medications, and other impurities from aquarium water, helping to keep it crystal clear.

Q: How does activated carbon work?

A: Activated carbon works by adsorbing dissolved impurities onto its highly porous surface, helping improve water clarity and quality.

Q: What does Elixr Carbon remove?

A: It helps remove tannins, dissolved organic compounds, unwanted odours, medication residues after treatment, and substances that can cause yellow or cloudy water.

Q: Will Elixr Carbon remove ammonia, nitrite, or nitrate?

A: No. Activated carbon is not designed to remove ammonia, nitrite, or nitrate. Biological filtration and regular water changes remain essential for controlling these compounds.

Q: Is Elixr Carbon suitable for freshwater aquariums?

A: Yes, it is suitable for freshwater aquariums, including planted tanks and community aquariums.

Q: Can I use Elixr Carbon in marine and reef aquariums?

A: Yes, it is suitable for saltwater and reef aquariums where maintaining clear, clean water is important.

Q: Where should I place Elixr Carbon in my filter?

A: It should be placed in an area of good water flow, typically after your mechanical filtration so debris doesn't clog the carbon.

Q: Should I rinse Elixr Carbon before use?

A: Yes, rinse it thoroughly with clean RO water before placing it in your filter to remove any fine dust.

Q: How often should I replace Elixr Carbon?

A: Activated carbon gradually becomes exhausted and should be replaced regularly. The replacement interval depends on your aquarium's bioload and water conditions.

Q: Should I use activated carbon all the time?

A: It can be used continuously for improved water clarity or temporarily after medication treatments to help remove residual medications.

Q: Can I use Elixr Carbon while medicating my aquarium?

A: No. Activated carbon can remove many medications from the water, reducing their effectiveness. Remove the carbon before treatment and replace it afterwards if recommended.

Q: Will Elixr Carbon affect beneficial bacteria?

A: No. Activated carbon provides chemical filtration and does not remove the beneficial bacteria living in your biological filter media.

Q: Is Elixr Carbon safe for fish, shrimp, and plants?

A: Yes, when used as directed, it is safe for freshwater and marine fish, shrimp, aquatic plants, and other aquarium inhabitants.

Q: Can activated carbon be recharged or reused?

A: No. Once activated carbon becomes exhausted, it should be replaced with fresh media to maintain effective filtration.

Q: Why choose Elixr Carbon?

A: Elixr Carbon is a high-quality activated carbon that helps keep aquarium water crystal clear by removing dissolved impurities, odours, tannins, and medication residues, making it an excellent addition to both freshwater and marine filtration systems.
