my DT is ready to go, I've had my QT running about a week with some live rock from the DT and some bacteria in a bottle, it will drop the ammonia to zero in less than 24 hours from 1 ppm, but nitrites are still high and nitrates are starting to show up, my understanding is that nitrites aren't harmful in a saltwater system so my question is if i do a 50% or more water change and it still drops the ammonia then is it safe to put a few fish in to start QT?
