Around a month ago I noticed some "grey" spots on my red monti cap. A week later another red monticap was showing the same signs. Then a couple weeks ago my green monti began to show issues and even has some brown algae growing on it.
Before these monti's were growing at ridiculous rates. Both of them in the pictures started as small 1" x 1" pieces a fellow reefer broke off his own colonies only 5 months ago.
I initially thought it was a potassium issue when the red plate showed grey but it tests at 400 using salifert.
As you can see the red cap has really degraded especially in the last week. It used to be so vibrant and red.
