xPremium filtration for freshwater tanks
Designed for PF-L power filters, the six-pack offers a reliable supply of replacement cartridges that fit PF20, PF30, PF40 and PF75 models. Each cartridge measures 6 by 4.5 inches, delivering a snug, easy-to-slot replacement that minimizes downtime during routine upkeep.
Four-stage filtration combines a dense cotton layer, a robust activated carbon bed (30 g), and a 15 g zeolite core. The resulting blend is intended to tackle cloudiness and dissolved impurities, potentially improving water clarity and supporting a balanced aquarium environment for fish and plants.
- Dense cotton for mechanical filtration and sediment capture
- 30 g activated carbon to absorb odors and pollutants
- 15 g zeolite to target ammonia and some heavy metals
- Overall design aims for stability in the water chemistry
The role of zeolite in this setup
Zeolite helps adsorb ammonia and select metals, which can influence the water’s balance. It may also support plant and bacteria-friendly conditions by contributing to a more stable environment and healthier feeding grounds for nitrifying bacteria.
- Adsorbs ammonia and heavy metals
- Helps moderate pH for a stable aquarium state
- Potentially supports plant growth and beneficial bacteria
Quick, owner-friendly installation and routine care
Getting a fresh cartridge in place is straightforward: rinse the new unit under clean water to remove dust, then insert it firmly into the flushing chamber. For ongoing water quality, regular replacement every 2-4 weeks is suggested, depending on tank load and filtration needs.
- Rinse before install to reduce dust and clogs
- Ensure a full, secure fit in the chamber
- Replace every 2-4 weeks for best results
