So I have a mixed reef with a sps
(acros, monti's, milli's), lps
(candy,frogspawn, acan, chalice, acan bowerblonki, favia, gonastria), lots of polyps zoanthids and such and some Xenia I can't seem to eradicate. My problem is for some reason my brain corals(favia, gonastria) deteriorate slowly and I can't figure it out. I've tried placing them in different parts of my tank but they still seem to be unhappy and recede. Let me know what you think the problem is cuz this is really frustrating me. I got the favia a couple months ago and this slow receding process is on going and now I got a gonastria and its not looking as healthy as when I got it 5 days ago.
Thanks for the input I really appreciate it
