Right, Juicebox. That's the way to handle filter media.
As regards API Quickstart. API does not identify the type(s) of nitifying bacteria they use. I'm not impressed with "Patented" bacteria. The idea of it's having a long shelf-life and not requiring refrigeration suggests that it contains heterotrophic bacteria, which is orders of magnitude less effective than the autotrophic bacteria that actually processes ammonia/nitrite.
Nitrosomonas and nitrospira are the bacteria that we try to cultivate. (They are present in the air---that's why a tank will cycle by itself, given enough time and oxygen.) A product containing those bacteria has a shorter shelf-life and should be refigerated (ont frozen). A company should be proud to specify that their product contains these live bacteria.
These companies do:
--MicrobeLift NiteOut 2
--Dr Tim's One-and-Only (shipped insulated from Dr Tim's)*
--Others that I can't recall right now.
Products which do not include autotrophic bacteria:
--Other heterotrophics that slip my mind.
Here's a great treatise by professional aquarist Carl Strohmeyer: That explains the difference:

*Dr Tim Hovanek marketed BioSpira,the first "Bacteria in a bottle," back in the 70s. He received his doctorate for the research leading to this.
