A: Yes, this is the correct cartridge for that filter.

A: You would receive one cartridge only, it is not a four pack.  The cartridge is pre-assembled and ready to use.

**Q: Will this work in the aqua tech brand?**
A: No, not very well as it is not quite the right dimensions.  You can use Penguin Rite Size cartridges depending on which size filter you have of the AquaTech brand.  For more help with your filter, email petsupport@spectrumbrands.com.

**Q: Will this work for tetra whisper 2-10i internal filter?**
A: Sorry, I don't know the number of my filter. It's the one that came with my Tetra 10 gallon tank
