Aqua One Betta Haven Carbon Filter Cartridge (2pk) 162C

This listing features the essential Aqua One 162c carbon and polymer wool cartridges as used in your 5l Betta Haven pico aquarium .

Usage
The 162c carbon cartridge is a disposable filter cartridge pack designed to trap solids and remove dissolved contaminants too – leaving your aquarium water fresh and clear. Each pack contains two cartridges. A 162c pack will usually last around a month to six weeks, though this will vary according to how much waste the cartridges have to deal with. When the cartridges are dirty, just throw them away and replace with fresh ones. Rinsing out is not recommended as this will not regenerate the important activated carbon layer leaving you with much reduced filtration.
