2 month old 15g Cube Aquarium

New 15g AIO Cube -- Goal: Mixed Reef
Introduction
I'm currently in college -- so I'm on the younger side. But still, I've been in the hobby for nearly 8 years. A few years ago, I had an 112 gallon Red Sea System but took that down when I left for college. After a hiatus, I gave in and decided to setup a small 15g system and I'm loving it!

Additional Aquarium Information

What do you think are the keys to your success in reefing?
Stability (no large water changes, no sand vacuuming, no excessive coral feeding)

This is the first time I have maintained a small aquarium -- and I'm prioritizing stability over everything else at least until my tank matures.
