Torch “issues” need advice/help

[Brian Berry]

I got this torch about a 2 month’s ago. My water parameters
Salinity 35.3. Nitrate 2.0, Phos. .01, Alkalinity 8.8, Calcium 470, Mag. 1480. My calcium and magnesium have been higher last couple of weeks. I am making my water now with Red Sea Coral Pro. Calcium usually around 430 and Mag. 1315. I see cracks all around base and a lot of receding.
The base was very brittle when I removed the plug. One pick the torch is in the very center. I included other corals as they appear fine. Pics are taken last hour of moonlight phase.

Low nutrients + high alk would be my guess, I'll let others chime in though.

Your nitrate and phosphate are very low for LPS coral. Fine for SPS but euphillia in particular like Nitrates 10-20.
Flow may also be an issue, They're pretty fussy corals, so you could try a slightly different position, even an inch can make a difference

Low nutrients and alkalinity. I will work on that. Thanks

I thought flow may be an issue. I angled more and set at a higher gph now. I will consider moving torch also tomorrow. I did not know that about euphillia. Appreciate the advice.
