Low Light Coralline?

I have a 25G tall SPS tank and it is growing Coraline algae under 2 x 55W PC bulbs.

I have a 50 gal and coraline grows right to the bottom. 3x 27 watt home depot daylight CFLs. They only have the 25 watters now.

I have deep purple coralline growing on rocks in my sump that get the spill of 2-400w halides at over 6' high and 3' away.

I thought so!! Thanks guys!

I've never been able to figure out why my tank doesn't grow coralline. I figured I could rule out lighting. The tank is 2 or 3 years old (can't remember), and there are only small patches of coralline. It's always been that way. It's an LPS reef, so obviously cal, alk, mag are all in check. I just can't figure it out...

Pour in some purple up, that should fix it! (kidding!)

But maybe?
