FAQ
How often should I replace the Fluval LIV Filter Cartridge?
It is recommended to replace the cartridge every 3 to 4 months, depending on tank size, fish population, and water conditions.
Can the Bio-Node media be used in a freshwater or saltwater aquarium?
The Bio-Node is designed for freshwater aquariums and is not suitable for saltwater environments.
Is the Premium Carbon effective in removing fish waste?
Premium Carbon is effective at removing organic contaminants and odors, but it does not directly filter fish waste. Debris is primarily trapped by the polyester pad.

The filter cartridge works well in my 20-gallon tank. Water clarity has improved noticeably after a few weeks. The Bio-Node helps keep ammonia levels stable, and the carbon removes the fishy smell. Easy to install and fits perfectly in my Fluval filter.

I’ve used this cartridge for about 3 months and it’s still performing well. The polyester pad keeps the water clean, and the carbon helps eliminate the odor. A solid upgrade from my previous filter media.
