Edit: Corals include 2 torches; 1 hammer; 3 zoa frags.
Hello all - I think my corals are dying in my 10g quartentine tank. These are my first corals, so I am a huge noob.
I bought them from LFS a few weeks ago. I have been pretty diligent with testing and water changes. they had been doing really well up until about a day or two ago, the torches and hammers arent extending fully and even through a day full of light they didnt reach full extension. These images are at the very end of my light phase where they have been becoming enclosed, but theyre just not re-extending over the last day or two. But up until that- they were thriving. Or at least it looked like they were.
Parameters:
Temp: 80.8 (to keep above 80.6 to shorten QT period shown on Humble Fish)
Salinity: 35ppm
PH: 8.2
Ammonia: 0.25 - 0.5 - trying to keep this down with 10% water changes every 3 days or so. It's higher than I want but I dont think this is cause?
Alk: 8.5-9.2
Calcium: 420-440
Mag: 1320
