coral algea (sp)

[seaapple]

Since my calcium level has been around 400 for the past 6 or so months, why am I not growing any coral algea? Does lighting, temp., and what else could play a part?
Any ideas?
Oscar...Thanx

Coraline algea, right?
Do you mean you have absolutely none, or just very little?
