Acan is loosing its slime and becoming rock

[Mike's Reef]

All of a sudden my Acan seems to be loosing its slime coat and becoming rock like. I have not seen any feeding activity lately. This coral used to show some activity late at night early morning. Not sure what to do. Any advice?

How are your water parameters? How close to the lighting is it? Water flow to high?

Actually it is a lobo brain
I guess my water flow is high from my vortech
It is on first level above sand
Light is a good distance but maybe I am hitting it with a lot of light
I will reduce light exposure to 7 hours on my illuminamagic

Lighting and flow kill acans first

 

[bizarrecorals]

whats your water perm?

+1 light and flow will do damage as well

I gotta say.. I have had several acan s for months now and no issues.. But in my previous tank I had thriving acans and after about a yr, they all started to diminish.. I think sometimes there is chemical warfare in our tanks we don't see.. What other corals are in there?
