Looking good!
Keep testing the water for nitrates, phophates, and ammonia. Hopefully the denitrifying bacteria in your tank is keeping up with the added bioload quick enough. Dosing some bacteria if you aren't already doing it should help avoid possible spikes while your system adjusts to the new bioload.
Keep an eye on the bubbles. Typically when I see bubbles on my rockwork, it is only bad news. During the initial stages, the bubbles were a first indication that my tank was still cycling... which is not a good thing if you already have fishes and coral. Ammonia in a system can kill things very quickly.
During the latter stages, bubbles could be possibly dinoflaggelates, cyano, or some type of nuisance macro algae forming. No, you're not in imminent danger, just noting to keep on eye on it just in case. Could be no big deal at all. My old nano used to bubble all the time and I never had nuisance algae and it definitely wasn't cycling for 6 years. Haha.
Give a shout out to the club if you have any questions! Glad you are jumping right back into it after getting rid of the bigger tank.
