Stability works, no question about it.
As far as;
As long as there is someplace for bacteria to take hold, a food source for that bacteria, & a supply of 02, bacteria will establish itself. I have proven this many times over in established tanks by simply performing massive frequent water changes in the weeks prior to increasing my bio load in a tank. Sometimes by more than 10x the current load. In my case we have chloramine treated tap water, so with every large water change comes a spike in ammonia, which over time creates a large spike in the growth of bio-bacteria.
Yesterday I took on some fish from a friend with no real advance warning so no time to play around with water changes in the previous month, so I'm using Stability again. Stats on this tank are 6 ft 125 gallon, filtered by 3 established AC 500's. (110's) Previous fish in this tank was a single 7" cichlid, only resident in this tank for the past several months. Current stock as of yesterday AM - two 12" snakeheads, and five 5" clown loaches. Used initial double dose of Stability (1 cap per 10 gallons) - and 24 hrs later still no sign of any type of ammonia spike. I will continue with 1 cap per 10 gallons for the rest of the week and do not foresee any problems.
BTW - if it hasn't already been mentioned in this discussion, Seachem sells an Ammonia Alert device that sticks inside ones tank, they are very handy for checking for ammonia spikes when setting up a new tank, or building on established ones. The sensor is good for approx 12 months.

As far as;
For use with Stability you should be using "clean" filtering media not established as the Stability bacteria may not "take" if they have to fight or get eaten by another form of bacteria.
