Tagging along. Anecdotally, IME, bacteria-in-a-bottle products have been wasted money. I've never magically cycled faster with them, then without them, both FW and SW.
My ammonia method opposed to shrimp has been to add some fish food - frozen or dry, doesn't matter - and let it decompose and create ammonia.
In the other thread mentioned on my first post. I cycled first tank with 8ppm ammonia in 2 days and i repeated that test and cycled in 2 days again. Product that did it was Fritz Turbo Start 900.
Today i start on new study to be fair to manufacturers as most claim 8ppm was too high and may have killed bacteria or stalled them from colonizing.
So i will start with 2ppm and i am sure i will have results in 2 days. Stay tuned.
