I have noticed over the last few weeks this orangish colored stuff on a few of the rocks. Its not soft, or easily blows off of the rocks, it almost acts like a coraline, but I have never seen one this color before. All parameters are good, nh3, ates, ites 0, ph 8.4 salinity 1.025 alk and ca balanced. the 'problem area is almost dead center of the pic on the lower half of the rock making a ledge.
