Torch turning translucent

[AbjectMaelstroM]

Just noticed one of my torches (NY Knicks) is becoming more translucent (more evident with whiter lighting).

All 3 torches were in Coral QT for over a month under a Kessil 160 @ 90-100 par. I transfered them to my DT a couple of weeks ago and now started to notice this loss of color and becoming transparent.

This is them in QT.

DT:
1.026 SG
9.5 alk
8.45 ph (0.5-0.7 daily swing)
Temp 78
440 Ca
1440 Mag
Nitrate 10 ish (raised for dinos)
PO4 0.14 (raised for dinos)

Par around 100-110 on the bottom med flow.

Any ideas?

That's what I'm thinking, just trying to figure out what the cause/solution could be.

How low was your PO4 and nitrate and for how long? Hopefully will improve with higher nutrients

PO4 and NO3 werent bottomed out, but NO3 was 2 and 0.03 Po4 or so when dinos happened, but the torches weren't in the DT then and were just recently added (2 weeks maybe less).

The entire time torches have been in the DT, the nutrients have been 10:0.15 N : P.
