How can I help my torch?

[Daniel Z0112]

How can I help this torch. It looks like it’s getting worst everyday. My frogspawn and other coral are doing fine. Could there be some pests?
I does kalk in my ato. 5 gallon biweekly water change. I only test alk with salifert. Alk is been stable at close to 9.
Any help would be greatly appreciated.

Do you feed them? Have you tried feeding them? Sometimes my torches look upset while my other euphyllia look normal. They always bounce back.

I just fed them some reefroid. I dont remember the last time I directly fed it. Maybe 3 months ago. Thanks for the help. I hope it can recover soon.
