Digitata problem

[JWorth]

Had a couple spots like these pop up so I blew off the "fuzzy" part and it subsided for a week or so and this morning, I have these new spots. What is this going on? All parameters are spot on where I want them. I did have a calcium reactor clog up with no pH controller, but I didnt let that water get into the tank. No new montis added in a long time. Added a few acros but didnt dip one so I could save the acro crab in it.

I should also mention that no other Monti's in the tank are showing disease and I have not seen any Nudibranchs and I have been looking.

I've seen that from time to time on my digis as well. When you blow it off, is there any damage to the polyps below it? If there is no damage to the polyps, I wouldn't be concerned. It could be food or waste from some other livestock that was captured by the polyps or it could just be calcium precipitating within the system. What are your Ca & Alk levels and have they been stable?

No polyp damage but it always look like a little tissue damage. It grew back before it did it again.
