Frequently Asked Questions
Q: Who are these large filter cartridges for?
A: They are for aquarium owners using a compatible Tetra Whisper filter that requires the listed large cartridge format. They are not universal aquarium filter inserts.

A: The listing names 20i, 40i, IQ20, IQ30, IQ45, IQ60, PF20, PF30, PF40 and PF60. Check your exact unit's instructions and cartridge requirements before ordering.
Q: Is this a practical gift for a fish keeper?
A: A refill pack can be a useful aquarium-care gift if you know the recipient's exact filter model. Confirm compatibility first rather than choosing by aquarium size alone.
Q: How should I install and replace the cartridges?
A: Follow the filter manufacturer's preparation, installation and replacement instructions. Disconnect powered equipment as directed before maintenance, and continue regular water testing and aquarium care. Do not rely on a cartridge alone to maintain water quality.
