Red Dragon Acro turning white

[Silly clownfish]

I got a few new frags about a week and a half ago and they are currently all in my QT/frag tank. My Red Dragon Acro is not doing well. See photo. One entire arm has turned white. On the opposite side I also have some kind of white worm-like growth that I can not pick off. The frag was dipped in Coral Revive, but that is not a treatment. It might have brushed against my new Chesterfield acro during dipping. I am afraid something like a FW dip will hasten its demise from whatever is turnin it white.

Tank parameters:
30 g with HOB filter using carbon cartridges, skimmer, circ pump. No sump, no fish.
Salinity 1.026
Ph 8.4
Alk 9
Nitrate and phosphorous unmeasurable
Ca 460
Mg 1420

Lighting is 2x 96W VHO bulbs, superActinic and Actinic white. They were about 7 inches above the coral and on for 11 hours/day. I just moved the lights up about 4 inches and dropped the photoperiod to 8 hours. But I would think if the lights were too intense the tips would bleach, not one side.

The only other living things in the tank are chesterfield acro (this is about 2 inchs away from the side that is turning white - I did not think acros engaged in chemical warfare wit each other unless touching), gorgonian, Blasto - both about 6 inches away, several frogspawn frags that I a growing out for trade at the far end of the tank. The frog spawn had been closer, but always at least 6 inches away. Could this be poisoning the tank? I could take these to the LFS to eliminate that risk.

Any constructive advice?

Thanks,
Kim

Looks like STN, No3 & Po4 undetectable? maybe try to bring a little more nutrients into the system.

overall pic of tank please

you mounted it upside down lol maybe increase the flow on that side and if your tank is ulns maybe lower the alk to around 8

This photo of the entire tank was earlier today. Red dragon is on the upper shelf on the right. Since then the frogspawn frags have been taken to the LFS and i moved the red dragon to that shelf an moved tolower left. Also adjusted the lights even higher. This is just a QT. Obviously nothing is going into my DT for quite a while.

I started adding nutrients a couple of days ago. Alterpnating between the water I thaw fish food in & reef snow. That has made the gorgonian happier ( it is photosynthetic, so doesn't technically require daily feedings).

Will keep everyone posted.

Thanks for the input.

Nutrients, or lack thereof was my first thought as well. More so nitrates than phosphates. You can buy planted aquarium nitrates in the form of potassium nitrate and calcium nitrate from various sources. I dose both to keep nitrates detectable.
