I have started cycling my new reef tank and have a question. I am using Dr Tim's bacteria and ammonia and dosed according to the instructions. My question is am I supposed to keep dosing ammonia after levels start to go down? The way I read the instructions I think I'm only supposed to do one dose and keep testing for ammonia and nitrite. I'm asking because I'm wondering if the bacteria that convert the ammonia start to die off after the ammonia is a 0 while I'm waiting for the nitrite to come down? I hope this isn't a dumb question.
