lack of coraline :-(

[michika]

Coraline has a direct link to magnesium; something about how they need to uptake it to balance out the Calcium. Anyways its in the Reefkeeping.com archives if you're curious for the longer read. The short version is though that you might find you get better, more robust, growth when your Magnesium is balanced. That being said, its always good to cultivate mutiple strains of coraline, nothing wrong with a few scrapings here and there from a variety of good sources. I found it took my tank about 8 months before my coraline really started to take off.
