Stability has bacteria that mainly focus on consuming ammonia and nitrite. This is great for fresh and salt water.
Microbacter contains 7 different bacterial colonies that consume ammonia, nitrite, nitrate, phosphate, and organic carbon. In a salt water, this product is enhanced by "carbon" or "vodka" dosing. Once the bacteria consumes the carbon, phosphate, and nitrate it will be consumed by filter feeding invertebrates or removed by the skimmer.
Microbacter is generally more expensive, so if you don't NEED it for fresh water, just stick with the stability.
As far as the shrimp goes, I have never actually tried that! I have always assumed that it would take at least a week or so for the shrimp to begin decompose. Some people add pure ammonia, some people pee in their tanks.... Not me.
I've just added fish very slowly, dosed bacteria for a longer duration than factory reccomends, and fed lightly.
