I know how people feel about "cycles in a bottle". But Marc Weiss' Bacter-Vital isnt really one of those gimmicks. I have seen 7 tanks (of which 2 are my best friends) that were cycled using Bacter-Vital, and out of almost 2 dozen fish, only 1 has died since the first tank was started last April. I followed my best friends tanks for 8 months before I even purchased my tank and equipment. Thats 8 months of close monitoring and study.
I have also seen my ammonia and nitrite spike on paper, as I have been recording all of my test results while using the Bacter-Vital. At this moment, my Nitrate is spiking, but still under 0. When using Bacter-Vital, your Ammonia result is multiplied by .0009, and your Trite and Trate results are multiplied by .000912. Your levels still spike during the cycle, they are just suppressed.
