It just got real

Your best move was posting here! Welcome and we’ll help balance your chemistry. My best advise I can give you for a new system is routine water changes and test water every chance you can weekly at minimum. A close friend drilled that into my head. Ever since weekly (sometimes bi-weekly) water changes and checking water parameters my system really started to thrive.
One more point, corals love reef roids and spot feeding but also POOP! feed your fish the best you can and your corals will thank you! A tang and some Nori will do wonders
