I would add more live rock
You're going to need about 24lbs of it total and it's more interesting to watch than a bare tank while it cycles
It's usually a safe bet to give it a couple weeks or a month before adding anything in the way of fish or corals but you can add some CUC (clean up crew lik snails and crabs) once your cycle is finished.
Do you have a test kit to monitor your water parameters? That will help tell you when you are ready to add fish and corals.
Best advice to live by in this hobby: be patient! It's hard but it's better than a tank crash!
There are lots of folks here to help you at Canreef, welcome!
