Also I don't understand what is wrong with Stress Zyme when you need all the bacteria when your tank is crashing, and you are doing to many water changes killing your aquatic cultures.

It's better than nothing but as far as accomplishing anything using it, the last test with the product had it take 30 days worth of additions by package instructions before any population of bacteria strong enough to create a nitrite level of .5ppm was in place. Under the same test conditions Cycle by Hagen accomplished that in 7 days and Bio-Spira by Marineland accomplished that in 3 days.
In other words, if a tank is in distress, for slightly higher bottle prices you can achieve the result you're trying to accomplish several weeks sooner.
I also have test results showing daily gravel vacuuming with 50% water changes not preventing the bacteria bed from developing and in comparison to a tank that had identical 50% water changes without the vacuuming, the vacuumed tank only took a couple extra days to cycle the first time and when the tank that wasn't vacuumed finally was and both tanks were spiked with equal amounts of ammonia, the tank that had been vacuumed all along had developed a much stronger bacterial population in places that couldn't be damaged by gravel vacuuming in the future where the tank that had never been vacuumed took much longer to redevelop bacteria to handle the ammonia. In other words, the more you vacuum the gravel, the more you encourage the bacteria to develop in places that will be permanent homes for them.
A secondary observation from that set of test tanks was 50% water changes and even vacuuming at the same time were incapable of keeping the nitrite levels down when the fish were continually fed twice a day throughout. Neither action damaged the bacteria enough to prevent the bacteria from cranking the nitrite off the chart every day from the ammonia released from fish waste and food.
Another interesting note now that I think about it, both of those tanks using no bacterial innoculation other than whatever developped from fish food and fish waste outperformed Stresszyme in the recent test. Both had testible levels of nitrite greater than .5ppm by day 12.
