New tank question

[reef-keeper]

As far as your question about adding more live rock after the tank has cycled you might get another major spike in ammonia. Due to the die off of the freshly added new rock. If you are going to add more rock it is best to add during the cycle stage. That way you don't create a new cycle, that just creates stress on the inhabitants of the tank. This I learned by trial and error killing off several fish in the process.
