Hi all. New member. Just got New Tank 73 gallon up and running. We took rocks from an existing 30 gallon Tank plus New live rock and sand plus some water from the existing Tank. We have 5 chromis in the tank too. It's been up for 6 days and the ammonia levels only reached .25 ppm for one day and nitrites are 0. We added quick start. What is delaying the cycle? Could it be stable since we aren't bio-loading the Tank? Help anyone.
