using non bubbly liquid ammonia with no brytex for cycling worked really well for me, my tank was perfectly cycled in a week with a few drops of liquid ammonia daily until ammonia levels spike then reduce drops to half then the nitrite will spike then stop adding liquid ammonia the ammonia and nitrite should level out and to get rid of nitrate at the end do a larger water change make sure u do this with everything in your tank gravel decor and especially your filter running the whole time. You can speed up the process by adding some gravel from your already set up tank into the filter. This will only work efficiently if u have a ammonia nitrite and nitrate test kit or else it is a real pain. This is only one of many options for quickly cycling your fish tank u don't have to go with this.
