Fluval Ammonia Remover Cartridge for C3 Filter, 3 x 140 g

Fluval Ammonia Remover Cartridge for C3 Filter, 3 x 140 g is a three-pack of replacement cartridges formulated to reduce dissolved ammonia in both freshwater and marine aquaria. Each cartridge contains a sorbent material selected for ammonia adsorption and is sized to fit Fluval C3 canister filter housings. The cartridges are intended for routine use during filter maintenance to help stabilise water chemistry and support the well‑being of fish and invertebrates.

Advantages

These cartridges provide targeted removal of ammonia without introducing chemical additives that change water parameters. Supplied as a set of three 140 g units, they allow for staggered replacement during regular maintenance and ensure continuous ammonia control when installed in compatible canister filters. The product is compatible with Fluval C3 filter models and designed for straightforward insertion and removal during routine service.

Suitable for

• Freshwater community and planted aquaria where biological filtration is established
• Marine and reef tanks for control of dissolved ammonia
• Quarantine or hospital tanks during short-term treatment to reduce toxic ammonia levels
• Routine maintenance cycles to complement mechanical and biological media

Key specifications

• Quantity: 3 cartridges per pack
• Net weight per cartridge: 140 g
• Media type: ammonia-specific sorbent material designed for adsorption
• Compatibility: designed for Fluval C3 canister filter housings
• Intended water types: freshwater and marine aquaria

How to use

Turn off and disconnect the filter according to the manufacturer’s instructions before accessing the media canister. Remove the used cartridge and insert a fresh Fluval Ammonia Remover cartridge into the designated media tray or compartment for the C3 canister filter, ensuring correct seating. Reassemble the filter, restore power, and check for proper flow. Replace cartridges at regular intervals or when water tests indicate rising ammonia levels; dispose of used cartridges in accordance with local regulations.

Usage recommendations

Test aquarium water regularly for ammonia, nitrite and nitrate to determine cartridge change intervals. Use these cartridges as part of a filtration strategy that includes mechanical and biological media; do not rely solely on chemical adsorption to manage chronic water quality issues. When treating elevated ammonia, combine cartridge use with partial water changes and address underlying causes such as overfeeding or inadequate biological filtration.
