That product is used for getting you water extra clean -- what some call "polishing" the water. It's not a necessity, but good to use on ocassion, or a little while after a water change. I have the Vortex XL, it is also a diatom filter.

We both run canisters, but this is used in conjunction with on part time basis. You run it to make your water crystal clear, especially after water changes.
