Tank started 9 months ago - I used dry base rock (from Caribsea) - rocks have turned green, which I'm told is normal. I have frags in the tank with purple coraline algae on them, but there hasn't been any indication of the algae growing on anything else. I had a few spots on the rocks, but it didn't last long - they faded away.
Ca is always kept at 430ppm and all other parameters are in check. Not sure if there's something environmental that coraline algae needs to grow and thrive? Or is the tank still immature and needs time before the algae appears?

From the sounds of it, although as nice as it looks, it introduces some high maintenance, so perhaps better not to have it?
