I just filled up a new tank I've been in the hobby for 20 years maybe I should know the answer to this question. I'm starting off with all dry rock Carib C and some dryed out live rock. I put 40 lb of live sand in, and I'm going to put in some Dr Tim's one and only and also Dr Tim's ammonium chloride solution once I read the directions. My question is I was going to add a couple pieces of live rock to my sump. I'm wondering if I should wait till this tank goes through its ammonia and nitrite cycle and then get a couple pieces of live rock in a couple weeks or so. What are some of your thoughts? Thanks ahead of time for your responses
