95g CO2 cartridge system (Fluval) is used to supply carbon dioxide (CO2) to an aquarium. The CO2 is used by plants and algae in the aquarium for photosynthesis.

Aquariums with live plants typically require a CO2 cartridge system to maintain healthy plant growth.

Our 95g CO2 cartridges, like Fluval CO2 Refill Cartridges, have a 5/8 thread. They are compatible with the Fluval Pressurised CO2 Kit. (We also have 45g Co2 Cartridges)
