There could be many reasons for this, we need to identify the issue before doing something drastic like interceptor.

Things like, pH swings, temp, the coral being shadowed by something, toxin war between corals, fish harassment, etc could all play a part. Try starting with the typical culprits like maybe new lights or bulbs or pH swings... had any of those happen lately? This could be especially true during the summer months where evaporation is high and you happen to use Kalk as makeup water.

Inspect the coral to see if it has any parasites like flatworms or bugs too.
