I have some button polyps that I've had for almost 2 years. They are starting to have white "blotches on them". I have approximately 7 colonies spread out throughout the tank and it's happening to almost all of them.
They're in my 210 gallon (that has been set up for almost 3 years)under 150W MH lighting, they've been in the same place for 6+ months, I have not added anything to the tank except a mandrin fish, haven't changed my salt, maintenance or anything.
Any ideas?
