chitons...all of the ones I have had are fine

look for things like AEFW. Any swings in the big 3 in the not so recent past?

I have seen something similar in my tank they never seem to bother my corals IME.

Those are safe...do you have pix of the corals that are not doing so well? That will help trying to figure out was is going on in your system. hth

I have had AEFW a few years ago, its not them. Something is eating them, i turned off the lights, look at night, can't see anything. I dipped them several times, nothing. All the params are fine. Something is eating at them. Guess i will keep looking...

I am quoting so your pics show up for other people. What kind of fish/livestock do you have?

Dip one that's having an issue in a 2 to 3x concentration revive dip. Make sure you get the rock or plug it is attached too. Look for very small skinny redish brown worms. Look like small bristle worms. But under further inspection they are actually very small Eunice worms I believe. But my corals looked just like yours. Slowly stn but one thing I did see was the bases would slime a little when I first turned on the lights. Just wanted n little spots. But they won't live on the coral.
