Ok, my ammonia has been at 0 for about 2 weeks, my Nitrites have been at 0 for about a week and a half, and my Nitrates have been stuck on 30 for about a week. I'm going to do a 10 gallon change tomorrow and hopefully see nitrates go down. I've been cycling for about 35 days and the rock came out of a completely established tank (thanks again juandean) The tank is a 55gallon and I've got about 75 pounds of live rock and 60 pounds of sand. A small refugium in the sump with Cheato.
The question, is it "safe" to add a fish after the water change? Also, do you add all the fish, then start adding coral, or is it the other way around. Start with coral and then move into the fish? I've heard both, and want to do it right. Thanks a bunch for the help.
