I have never done or needed to cycle a tank. I set the tank up, drop a few fish in it, add a few pieces of media and decor from an existing tank, and if I think that I need some help I add this. https://www.fritzpet.com/turbo-start-700/
I set up my 300 Red Devil tank, everything was new. The only thing I added was existing media from another filter, a couple pieces of wood, and 10 Red Devils ranging from 6"-12". Around day 5 the tank became a bit cloudy, I added the above bacteria, and no issues. All this was done in 1 week and fish enjoyed their home immediately.
