Same here, 2 months....been told the same that it is part of the natural new tank cycle, my emerald eats some and the cerith and turbos put a small dent in it but I mostly sucks it off the rocks with a siphon when I do water changes. The rock underneath is turning green now which I have also been told is part of the cycle and then I should hopefully get some coraline going after that.
All you can do is keep your parameters where they should be, suck as much out as possible during changes and keep that skimmer running.
