Milles bleaching?

[ThorEffex]

ive noticed latley that most of my millis are bleaching or browned out. The worst bleached milli has had hermit crabs making it their home. But the others they don't touch. My system is running on doesing pumps and is fairly stable week to week. I do run radions at 50% power for the last six months and all acros look good. I also haven't added anything new in months. So my question is what do you think is the problem?

Currently
Salinity: 1.025
Ca: 420
Alk: 8.1
Mg: 1350
Phospates: 0 (I do feed heavily)
Nitrates: 0.5

Check the underside for worms? Some more derail would help. Parameters, any recent changes, etc.....

I have a Pink Milli frag I just picked up about 2 months ago. It looked great for about 6 weeks and then all of sudden it went nearly white. I checked for every kind of pest and found nothing. I checked all water parameters and they were consistent with when it looked good.

I dosed aminos heavily and the color started to come back. I continued to dose and it's looking like it did when I first got it. In fact a little better color now. There are several other acros and montis in the tank and nothing else showed the sudden and rapid loss of color. Everything looks better with the addition of AAs.

I have always fed and added AAs. What I didn't consider was how much growth I'd had over the last few months and how many frags I'd added. Once I compensated and dosed more AAs I'm back to good growth and color.

I have pulled a couple of the corals out and dip/ inspected then and I did not see any worms. In the last eight weeks it has been going good not much in change their is a lot of automation on my system. I did remove a large coral and replaced the rock it was on with a piece of dry rock maby four weeks ago now. But it was about a pound rock on the posit corner in a fifty gallon aquarium. I'll pull out the cutters and try to free the bleached Mille for a dip. A few days back I did add a wrasse to my tank but this problem was already under way.

I do dose acro power at 2 ml/day. I'll give it another ml/day. The tank has been up and running for about two years now. And I find there is a fine line of how much stuff to does before it browns out.
