Finally got rid of the dinos a couple of months ago and now in the past couple of weeks I have this pinkish/brownish/rusty dust-like stuff appearing on the sand bed. Thought it might be cyanos but doesn't form a sticky mat. If I lightly stir the sand, it goes into the water like a dust cloud only to regrow later. There are patches growing on some of the rocks which don't become dusty as the stuff on the sand does. My Diamond Goby doesn't seem to want to eat it either.
Any clues as to what it might be? Suggested treatments?
Thanks in advance!
