My tank finished cycling about a few weeks ago. Ammonia and nitrite was 0 and nitrate was 5. I just put in 3 12" banjar a few days ago and the ammonia is 0.5, the nitrite is 1.0 and the nitrate is 10. Should I use amquel+ to lower these levels or just wait for the filter to take its course. Its 150g and I'm using xp3 filter. Any suggestion?
