Phosphate: <.03
Nitrate: 3-4 ppm

If my alk and calc are on point it is normally on point. It was 1350 last week. I will check but it shouldn't be off.

Anything

I see you have a 35g, how are you keeping alk stable. Also, the PE looks much less in the second pic, have you ruled out pests, nippers, etc? Last, could simply be starving is all.

They may not be adjusting to the lighting well. And I've seen some SPS just do horrible under LEDs while others flourished.

Pests would be another concern. What method do you use to ensure you don't have pests?

How long have you had it? I don't see any discernible growth from the pic. So I'm guessing it's happened fairly quickly? If that is the case, I would lean toward the lighting. Maybe reduce the whites and/or put a few layers of window screen over the new frags.

Sorry, forgot to mention, right is when I got it.... Left is now.... I don't know why I did the layout that way. My akl is very stable. It doesn't fluctuate barely. I dose to keep it stable and it stays pretty much right at 8.3-8.5. Everyday I feed pellets at noon ish and later in the evening I feed either some cyclopeze and half a cube of mysis or a chunk of rods food. And at night I put in a capful of marine snow every other day.

I'm thinking the same thing with the lighting because it went from 20k halides to LEDs. I keep really good close watch on these guys everyday and I'm pretty sure I don't have pests and I have an acro crab in one so he helps a little. Not sure of the exact name but my other purple acro has seen some great growth so far. It has encrusted a decent amount in the month it's been in there. I thought that it could not be getting enough light.

In that case, good job, PE looks good. Look at lighting and PO4 now and keep it stable.

PO4 is good. I think it is lighting IMO... just not sure. I'm scared to raise it too fast.

Yep, go slow and it looks to be doing well as stated. GL

Thanks! its not dying! Losing color is much better than that but im gonna bet it is the transition to LED and not enough light yet
