    My corals both SPS (e.g., spongodes montiopora,montiporal-capricornis orange) and zoas are growing very well, but they just lack color. Is lacking color generally a result of too much/not enough light.
    I have been having some issues with calcium not being high enough. I'm relatively new to this and just discovered that I needed to check magnesium as well as all of the other things. Yesterday I added Mg for the first time, check it today, and it was still low. So I added more today.
    My other parameters are great.

    "Great" makes it hard to diagnose what's wrong.

    Lighting can cause color loss. what lighting are you using?

    Phosphates also affect color and eventually growth.

    It is important to have calcium and magnesium at correct values for coral health. What you're doing is a good start to recognize that. :)

    It is a dry heat, yeah right !
    Try dimming your lighting a little if possible and feeding more if nitrates and phosphates are not already elevated.

    Could be from starvation. Are the brown, pale, white?

    Need to check your nutrient levels, phos and nitrates. Too much, corals brown, too little corals pale. Put up some pictures of your corals if you would please.

    What salt are you using? I really believe that a healthy, thriving reef starts with a good salt...
