Lobophyllia dying - help?

[Sonam]

This lobophyllia has been in our system for a few weeks. Initially it was doing well and over the past few has really died back. We have another in the same system that is doing perfectly find.

Any ideas? Did an iodine dip as a start.

Nitrate 16ppm

Phosphate 0.36

Calcium 400

Alk 10.5

Sg 1.025

T 77.1

Any corals within the vicinity?, have you tried target feeding? Is it getting enough light? Too much?, have you introduced anything that maybe detrimental to coral in the slightest?

Target feeding and make sure not too much light and flow

Will try target feeding. I am wondering if the flow is a problem. We have a second one that is doing really well.
Haven't introduced anything that we know of but one thing that crossed my mind is we are fishless after a marine velvet outbreak. There have been no fish in the tank for a month and we've noticed an increase in amphipods and copepods, as well as some ghost flatworms and other tiny crawlers on the rocks. Wondering if any parasite normally kept in check by our 6 line wrasse are starting to get out of balance.
Our wrasse is alive and well thank goodness - in a QT system while we let this one stay fallow until the marine velvet or ich is completely eliminated (at least for a while).
What do you guys think? Could it be a critter irritating the coral?

Is this lobo getting stronger light than the one that's doing well
I can see from the pic that it's up on a rock
Maybe it's getting to much light to soon seeing as it only been in the system for a few weeks ....just a thought

Thank you. It is a bit brighter yes.
