Hola
Thank you for sharing the photos of your beautiful corals! They all look quite healthy to me. My opinion of additives are as follows:
Calcium = 380-420ppm
Alkalinity/KH = 2.74-3.25 meq/L or 7.7-9.9 dKH.
Magnesium = 1300-1500ppm
I have used Iodine additives over the years but haven't seen any good or bad results so I do not add it now for the past few years.
Most SPS corals especially Acropora species change color due to changes in light intensity, spectrum, and duration (length of photo period). Other factors can cause changes in coloration but in my experience (IME) lighting is the number one cause. Be sure to note that coloration is NOT an indicator of coral health but rather an adaptation to its environment.
I do not feed any of my corals except what they get from food I feed my fish. I feed the fish a mix that contains:
Formula One frozen cubes (I vary the type of cubes).
Chopped raw shrimp.
Freeze dried plankton.
Dried seaweed.
Cyclop-eeze.
Crushed garlic.
I feed once a day but sometimes twice.
Saludos,
Kevin
