Welcome to the site. Make sure you use a ammonia calculator. When using the calculator have a set ammonia reading that you would like it cycled to. Like when I did my saltwater tank first cycle I dosed it to 4ppm of ammonia and waited until it was at 0 ppm
( could take days) but after awhile I could take 4 ppm
of ammonia and get rid of it in 12 hours and nitrites would be gone in 24 hours. I ended up doing a huge water change to get the nitrates levels down to a safe level.
