Activated Carbon for Aquariums sera Super carbon 29 g - aquarium filter media

sera Super carbon is activated carbon in a 29 g package formulated for use in aquarium filtration. It removes dissolved organic contaminants, discolorations and odors from the water column by adsorption, helping to restore water clarity and maintain water quality. The product is intended for use in mechanical and chemical filtration stages such as cartridge filters, canister filters and media chambers, and is suitable for freshwater and marine aquaria when used according to manufacturer instructions.

Advantages

sera Super carbon provides rapid adsorption of organic substances that cause yellowing and odors, improving visual clarity and reducing the load of dissolved organics on biological filtration. The granulated activated carbon is supplied in a convenient 29 g portion suitable for topping up existing filter media or refilling small filter cartridges. The product is compatible with common aquarium filter housings and does not release nutrients or additives into the water when used as intended.

Suitable for

• Removing discoloration and odors from aquarium water
• Use in filter cartridges and small canister filters
• Temporary polishing of water after treatments or medication
• Freshwater and marine aquarium filtration stages

When it may not be suitable

Activated carbon does not remove ammonia, nitrite or nitrate and should not be relied upon for biological filtration. It also does not remove heavy metals or permanently bind all types of dissolved substances; some specialized contaminants require dedicated media. Excessive or prolonged use may reduce efficacy over time as adsorption sites become saturated, so regular replacement is necessary.

Key specifications

• Form: granulated activated carbon
• Net weight: 29 g
• Intended use: chemical filtration/adsorption of dissolved organics
• Application: filter cartridges, canister filters, media chambers
• Suitable for: freshwater and marine aquaria

How to use

Rinse the carbon briefly in dechlorinated water to remove dust before placing it in the filter. Use the 29 g portion in compatible cartridge slots, small media bags or the media compartment of a canister filter. Replace the carbon regularly — typically after 2–4 weeks depending on bioload and water conditions — or sooner if water discoloration or odor returns. Do not use carbon simultaneously with phosphate-removing media in the same compartment unless manufacturer guidance allows separate flow paths.

What to consider before purchase

• Check compatibility with your filter type and available media space
• Consider aquarium size and bioload to determine replacement frequency
• Activated carbon does not replace biological filtration; plan media combination accordingly
• If treating medication, verify whether carbon should be removed during dosing

Usage recommendations

For routine maintenance, use sera Super carbon as a short-term polishing media after water changes, plant pruning or medication to quickly restore clarity. Replace the 29 g portion at regular intervals and monitor water parameters to determine the optimal replacement schedule for your aquarium.
