Water parameters are good.
Tank is very nice.
If ALK is at 3.0meq/l and Ca stays above 420ppm you will begin to have great coralline growth. Keep up on phosphate management now that you have a handle on things.
Don't worry Mr> Firemouth as some people may have a guessed I'm rather paranoid about PHOSPHATES so they won't be beating me again!!! There is already a fair bit of coraline growth but when I put the rocks back in, the majority has ended up facing the back of the tank or at the bottom!!! I enjoy watching how the tank "grows" so new growth will give me something to look forward to.
