Is my 130.4 Waterbox at max stocking or overstocked?

In my Waterbox 130.4 I’m running a skimmer with a 20% water change every 2 weeks. Rigjt now this is my stocking
- kole tang
- powder brown tang
- sailfin tang

I plan on adding
- 3 Anthias
- pair of purple fire fish
- maybe some others depending on my limit

Not even remotely close. I have 49 fish right now in my 160-gallon display (no water changes, but I do run UV and ozone). This includes 4 tangs, a foxface, parrotfish and 2 large angelfish.

That's dope, always wanted a large angel but it would eat my coral lol. I've heard of people adding ozone to their reef tanks and sw tanks. What does it do exactly?
