How do the PF-L cartridges filter aquarium water?

Each cartridge combines dense cotton, activated carbon and zeolite in a four-layer filtration design. The cotton provides the cartridge’s dense filtering material, while activated carbon helps remove odors and reduce water turbidity. Zeolite adsorbs ammonia, heavy metals and other harmful components in the water, and is included to help balance pH and support a stable water state.

• The filtration design is stated to filter and absorb 99% of sundries.
• The combination of media addresses particles, odors and water components through filtration and adsorption.

Which power filters fit these replacement cartridges?

ELCCOTYA PF-L cartridges fit Top Fin Silenstream PF20, PF30, PF40 and PF75 Power Filters. Each cartridge measures 6 inches (15.24 cm) in length by 4.5 inches (11.43 cm) in width, so these are the measurements to compare with the cartridge space in your filter.

• Made as replacement filter cartridges for the compatible power filter models above.
• Check both the model and cartridge space when choosing filter media for your aquarium setup.

How do you install and replace a cartridge?

Remove the used filter element, rinse a new cartridge with clean water to remove dust, then place it fully into the filter chamber. The recommended replacement interval is every 2–4 weeks to help maintain clean aquarium water; the aquarium environment can guide timely replacement.

• Rinse the new cartridge before installation.
• Seat it completely inside the filter chamber.
• Replace the cartridge on the recommended 2–4 week schedule.

These cartridges suit aquarium owners using one of the compatible Top Fin Silenstream power filters who want replacement media with cotton, activated carbon and zeolite in one cartridge. They are intended for routine aquarium filtration and water clarity, with dimensions and filter-model compatibility that help identify the right fit. For compatible PF20, PF30, PF40 and PF75 filters, each replacement combines four-layer media with a straightforward rinse-and-install process.
