I am fairly new with my saltwater tank. I have been trying to keep it slow with additions although I am not sure if I need to wait and add coral slowly or if I can add as much coral as I want anytime. My water has tested excellent for the last 2 months. I have 3 fish in the tank now and several cleaners. I read that you should (which I have) add fish slowly but find nothing on how fast you should or can add coral? Any advice would be great.
