Is this a healthy and mature tank?

[jerallenttu1]

200 gallon Neptunian cube
Protein skimmer
Bioreactor

Current parameters:
pH 8.0
Ammonia 0
Nitrite 0
Nitrate 5.9
Calcium 380
Phosphate 0
Alkalinity 8.2
Salinity 1.025

10% water change ever other week with coral salt pro
AB+ every 2 days

So I have had my tank a little over a year and have never been able to keep coral except zoa's. I also could never keep nitrates above 0 for more than a couple of days after dosing neonitro. Now I have nitrates which are staying steady, coraline algae, and within the last week green algae on the rocks. I also rearranged the rocks so that the zoas were closer to the light and they really opened up over the last couple of days.
Anyway I am thinking of trying a new coral, but I read that zoas need very low par and could be almost on the bottom, but they are a lot happier about halfway to the surface in my tank. I have 4 AI Prime 16HD reef lights, were they just set up too far from the surface?

I don't like giving bad news, but 4 primes on a 200 gallon is very minimal lighting, these are nano tank lights. It will be a challenge to grow anything but the very lowest light requiring corals. These primes have a reputation of melting lenses, so be careful about turning it up to full power. You might want to consider adding more primes, or just upgrading altogether.

I ran mine full power and it melted after around a year and was the downfall of my first reef tank. I now use Kessil

I’ll add to the suggestion list and say your phosphates should be more than zero as well. You want them to be close to zero but not zero.

Agreed with more lighting needed. I would pull this trigger before adding new corals. And it'll be expensive. There are more inexpensive options out there, but to give you an idea, I'll most likely be running 2x Photon V2 Pro 48" over my 48x39x25. You can always explore used options as well (which is what I'm gonna do). LEDs last quite a while, especially when run at 30 to 40%.

As someone else suggested Primes are probably too little light for this tank. Not sure if changing the lights will mess up things with the screen top due to their mounts though.

The best lighting in my opinion are the Reefi Lights. They have a lot of power and spread for small lights and for the price they far surpass a radion or kessil. Another great option that is cheaper are the Nicrew Hyper reef lights. They are good lights, but I'd recommend buying the controller for them.
The last option could be getting QuantaReef light bars.
But Zoas actually can do well in a large variation of lights intensities. They will be more colorful under higher light though. And as long as you don't light shock them or give them an insane amount of light they will be fine. But they definitely benefit from increased light if they look very drab. It can take time for them to recolor up though.
If you want to direct message me for any other advice or elaboration I'm here to help

Thank you all for the comments very helpful. I feel like I never stop learning new things with this hobby.
Can I get some links to better lights or what specs I should be looking for? My LFS set all this up so I thought it would be good. And how expensive are we talking for new lights? Can I get good lights for under 1000 total?

What have others used to successfully dose phosphates?

Is the green algae on the rocks a good thing?

Also here is my light settings which were recommended by LFS.
