Is this tank at or near a window?
Are you by chance using tap water or tap water for topping tank off?
What is your phosphate level?
Seeing no coral on this rock, I would place it in a container of tank water and pull off as much as you can by hand and scrub the rest with a firm toothbrush and some 3% hydrogen peroxide.
Return to tank, reduce white light intensity and number of hours of white lighting and add some snails such as :
Astrea
cerith
turbo grazer
trochus
A Pencil urchin
8-10 Caribbean blue leg hermits
Another cause is overfeeding and lack of maintenance.
