Filter Media Ammonia Remover for Fluval C4, 3 x 290 g cartridges

Filter Media Ammonia Remover for Fluval C4, 3 x 290 g cartridges are replacement media cartridges designed specifically for use with Fluval C4 canister filters. Each pack contains three pre-filled cartridges with 290 g of ammonia-adsorbing media that target dissolved ammonia in freshwater and tropical aquariums. The cartridges are shaped and sized to fit the C4 filter cartridge baskets for straightforward installation during regular maintenance and cartridge swaps.

Advantages

These cartridges provide targeted reduction of dissolved ammonia to help maintain stable water chemistry and reduce stress on fish and invertebrates. Pre-filled cartridges simplify maintenance and avoid direct handling of loose media, while standardized sizing ensures consistent flow and compatibility with Fluval C4 canisters. Using purpose-made cartridges supports the mechanical and biological stages of filtration by removing a toxic nitrogen compound without altering other water parameters.

Suitable for

• Freshwater aquariums equipped with a Fluval C4 canister filter
• Home aquariums with tropical fish and community tanks
• Aquaria undergoing routine water-quality maintenance or ammonia spikes

Key specifications

• Pack contents: three cartridges, each containing 290 g of ammonia-removing media

How to use

Turn off and disconnect the canister filter according to the manufacturer’s instructions, then open the filter body and remove the used cartridge.

Reassemble the filter, reconnect hoses, and restart the unit following safe priming and leak-check procedures. Replace cartridges as part of regular maintenance or sooner if water tests indicate elevated ammonia levels.

Usage recommendations

For best results, monitor ammonia levels regularly with a reliable test kit and replace cartridges according to aquarium bioload and test readings. Combine ammonia-removing cartridges with routine mechanical and biological media care to maintain overall filter performance and water quality. Avoid using multiple chemical media types simultaneously unless recommended, and follow Fluval C4 maintenance guidance to preserve flow and filtration efficiency.
