This aquarium filter cartridge is compatible with Whisper Bio-Bag External Filter PF20, 30, 40, 60/ Whisper External IQ20, 30, 45, 60/Whisper 20i & 40i Internal Filter and TetraFauna ReptoFilter 50 gallons (125 GPH).
• Four-Stage Filtration: The filter is made of dense dual-sided mesh, with better thickness for improved filtration. Ultra-Activated carbon replaces ordinary carbon and processed zeolite is added, effectively filtering and absorbing impurities in the water to maintain a clean water source and provide a healthy growth environment for fish.
• Efficacy of Zeolite: It can adsorb ammonia, heavy metals, and other harmful components in the water. Effectively balances the pH value of the water body to achieve a stable water state. Zeolite can improve the fertilization efficiency of aquatic plants, enabling faster growth and a more comfortable, healthier environment for aquatic life.
• Quick Installation: Turn off and remove the used cartridge, then flush the new cartridge with clean, cool water or aquarium water to remove dust. After rinsing, insert the cartridge into the flushing chamber, ensuring it fits completely.
• Professional After-sales Service: Tip: We recommend replacing the filters every 2-4 weeks to maintain water quality (depending on the number of fish in the tank). We are professionals in the field of aquarium filter cartridges; if you have any questions, please feel free to contact us.
