Hello all, I started up a used 20 gallon BioCube tank with all bleached, dry rock. I am trying to cycle the tank using Reef Mature by Red Sea. I'm on day 10 and have had very little increase in ammonia and no nitrites or nitrates yet. There is also no sign of any algae growing. Can I go ahead and put a fish or two in or should I get a small piece of live rock and put that in first and continue cycling?
