IMO water quality is the factor when it come to health, growth and color in the tank.
So let me start with what I consider high quality water parameters.
Testing the water
SG: 1.024-1.026 Close to NSW levels.
Temp: 78-82
Ammonia: 0
NO2: 0
NO3: 0 or the absolute lowest level on the test kit.
PO4: 0 While you might have some phosphates in you water, they should never be high enough to register on a test kit.
Ca: aprox. 400
Alk: 8-12 dKH
Mg: aprox. 1300
pH: 8.0-8.3 should fluctuate as little as possible, typically no more than 0.2.

All good info, but I dont like one thing. Alk 8-12 dKH. I'm sure most of us here understand that you can run a healthy tank within those parameters, but you might find a guy that posts, "my DKH is 8.3" and someone tells him to raise it to 11-12 DKH. He trusts whats written here so he dumps in a bunch of B-Ionic to raise it up, figuring anywhere between 8 - 12 will result in a healthy tank. He bleaches or rtn's everything.
In my opinion, Alk is one of the most critical components of a healthy tank. We've read a lot recently of lower alk readings in healthy tanks. I believe this is because a lower reading will result in more stability. You find a level between 8-9 or lower, and you dont need to add anything to keep it there. Maybe dose kalk or keep your reactor dialed in.
I shoot for Stability. I even started using NSW, not sure if I have the Stamina to continue that practice, but what could be more Stable than a 10 gallon NSW water change?
I run a DSB ( I get the brown sand cyno about once per year.) My tank is algae free most of the time. I run Phosban and Carbon in a reactor, (most of the time) I'm experimenting with Vodka Dosing (This is another story I dont want to comment on right now, but I've been doing it for about 6 months.)
120 gallon
30 gallon sump refugium
ER 8-2+ Run VERY WET.
Approx 4000 GPH (Ocean Motion 4-Way)
250 DE 14K Phoenix Lights (Actinic Supplement)
Chiller (Temp Stability is So Important) 80-82 for me.
Kalk Dosing
CA 440
Alk 9.0 Slowly Dropping
Low Feeding
Everything is Healthy, not as colorful as the Zeovit folks, but I'm working on it. I've got a couple of nice new SPS coming on Thursday.
