Color and growth questions

[Dakotah]

I have a 125 gallon display with a 75 gallon refugium in the bottom. I have metal halides and dual 130 watt actic compacts. I feed red sea reef energy with flatworm stop. "I use flatworm stop because I was told it was basically roids for my sps... Idk if this is the case or not" but my question is what should I do more or less to get the most color out of my sps? I want like boom colors and for sps I have an Ora turquoise staghorn and two others that I don't remember the names any advice would be greatly appreciated I'll attach pics

Added note I have more pics but I'm having technical issues

that's always the golden question. The answer is Potassium dosing. That's when the real color boom happens

Yeah I'll go to the lfs and see about starting to dose that.. That's the only thing I don't dose really...
