Sorry. The best way is to add an ammonia source and let it do it's thing. If you really think it's cycled get bottled ammonia and dose your tank to 1 ppm if your bio filter can turn this completely into nitrate in 24 hrs (0ppm of ammonia and nitrite) then your ok, if not dose it up to 4 ppm and let it completely go to nitrate then do it again and once the second one is all nitrate you should be good
