About this product
These small aquarium filter cartridges are for the power filters in Koller Products and Hawkeye setups, and the manufacturer directs you to swap in a new cartridge monthly. Each cartridge arrives assembled with activated carbon and dual-sided poly-fiber floss, and the pack contains six. The cartridge measures 2.38" long, 0.75" wide and 5" high.
How do you install these cartridges?
The cartridge comes fully assembled, so it goes into the filter as it arrives. The manufacturer's directions are to replace the cartridge monthly to keep the filter performing as intended, and to replace it sooner if it is heavily soiled and water flow is reduced.
The cartridge's carbon core and floss layers
Activated carbon sits inside the cartridge, and dual-sided poly-fiber floss wraps the outside to catch fish waste and other debris. Because the cartridge is assembled, there is no separate media to add before it goes into the filter.
What the six-pack contains
- Six small replacement filter cartridges, each with activated carbon and poly-fiber floss.
- Each cartridge is pre-assembled for the filter.
- The pack ships in white SIOC packaging in some regions.
