Hello,
I have a Symphyllia Wilsoni in my 300 gallon mixed reef tank this is about 90 days old. The top of the coral started developing brown spots about 3 weeks ago, but now those spots have turned black and it appears the tissue of the coral is receding in those areas. I'm broadcast feeding reef chili, reef roids or marine snow a few times a week, plus frozen foods, pellets, flakes, etc - very good variety of foods. I'm looking for feedback on if and how bringing this coral back would be possible.
0 ammonia
0 nitrate
25 nitrate
.26 phosphate (just tested this today and added recommended amount of seachem phosguard to tank)
158 ppm (8.68) alkalinity (always in 150s)
430 calcium
1290 magnesium (dosed up 100 today)
