red coraline algae growth

[ricky1414]

i introduced a handful of astrea snails that had cool red coraline growing on their shells. soon afterward, approximately one and a half months later, it has appeared on most, if not all of the rocks. it started off as a light dusting, but has been progressively growing denser. I like the look of the red, but will it leave after I install my mh lamps?

I have posted 2 pics. I have not retouched at all, save for resizing. Any opinions or thoughts, feel free.

I've got lots of dense patches of that red growing on my LR, but no MH. I do see the purple coraline growing over it where it meets though. :?

Over the course of feeding, water changes animals coming and going, you'll see lots of different kinds of algae.
Once you add MH to your set-up, some algae
growth like that will be restricted to shadier zones.
