lack of coraline :-(

[toytech]

mine always grew in places where there was less intense light , lower rocks and shaded areas first . I took some time for it to take off in high light areas .

You should NOT complain. I got 4 tuxedo urchins to fight the coraline plus lots of elbow grease to scrape the glass. It is pretty hard on your Ca and alkalinity levels.
Be careful what you wish for.

Yes, I noticed that, too. And marco rocks for some reason, took longer, too.

+1, 19 months in and you're just now not able to tell the difference between my Marco rocks and my live rock. My black plastic encased over flow boxes however, are so thick with the stuff they're starting to look like columns of live rock.

I've got zero coralline growth on the highest, brightest points of my rocks.
