Hi I have had this monti for about year. The day I bought it and brought it home it had really bad tissue recession about half the coral had died off right around the center. Most of it grew back but not the very center where this algae is. Since probably about 8 ish months ago this algae has always been there it has gotten more full and died off then would grow back thicker and die off again, this cycle just keeps continuing. Is there anyway I can try to remove the algae??
