I just purchased my 29-gallon tank and have a few questions. \r\n\r\n1. I have live sand and 5lbs of live rock. I was told that I should have 15 lbs of live rock before I start adding any fish. Is this true? I want to begin by adding a couple of damsels. How long should I wait after adding the other 10lbs of live rock before adding the damsels?\r\n2. Should I wait until the PH and other levels (nitrites, nitrates, etc.) are where they need to be before adding the damsels? The salinity is reading at 1.024 is this a safe reading to add fish. I havenâ€™t tested the other numbers yet. \r\n3. When can I add the clean up crew to the tank? Should I wait until I have added a few fish?\r\n\r\n\r\nThanks!
