Getting a cartridge onto the power filter
A cartridge comes already set up, so it goes onto the power filter and is ready to use once installed. Before it goes in, clean any carbon off the filter cotton.
When a cartridge needs changing, it comes off without tools.
Dense cotton and a grid design
The filter cotton on each cartridge is dense, and the grid design holds it in shape. Each cartridge is already assembled, so there is no separate media to add before it goes on the filter.
How often a cartridge is changed
The maker recommends a replacement every 2 to 4 weeks.
What the 16-pack contains
- 16 aquarium filter cartridges
