Lobos and brains are dying

[nick 210]

My lobophyllia and brains are dying off slowly , why? While all my other coral is doing good ….. torches hammers mushrooms and zoanthids . Water parameters are
Calcium 500
Mag. 1350
Alk. 9.6
Salinity 1.022
Temp. 78
All this has happened within the last month. I can’t figure out why
Help!!

What other fish - if any do you have. I had the same problem - then I bought a lemon peel angel. Thereafter - coral after coral died. Then I took @vetteguy53081 recommendation - take a video or stand back - and I could see the attacks.. Hope this helps

Salinity very low for this coral - You want 1.025
Calcium a little high= get closer to 425-450 range
Placement makes a difference. Please post pics of coral to best determine its health
