I would give it an hour and check ammonia which should read very high. If in a couple hours ammonia is coming down but nitrite is high that would be a good sign. If in 24 hours ammonia and nitrite are 0 but nitrite is through the roof you have a good colony of BB that can handle a couple fish. Do the 10% water changes to get nitrate down below 20 and add one or two fish. Keep checking the water. You will most likely see nitrate rising but ammonia and nitrite staying at 0. That means the BB are doing there job. Give them a week or so to multiply before adding any more fish.
Man, I have learned a lot in 4 weeks. LOL. If anyone sees where I have said anything wrong please correct me.
