Coralline growth under LED?

Thought the heading sounded familiar! lol
I'm actually starting to get a fair bit of coralline growth at the moment however most of it is that nasty dark green you can get.
Maybe I was mistaking it for regular algae before, but its definitely growing like coralline now. There are a few small new patches of purple showing up, mostly on plastic plumbing. Also the purple that was there originally hasnt faded away so I'm hoping it will all turn a much nicer purple eventually.

 

I started my 34g solana with a Maxspect G2 110w fixture and have had very good coraline growth. The tank was started 10 months ago and the back wall is completely covered. Nearly all rocks were covered until a recent scape change that added some new rock. It's been growing quite well.

 

under my AI sols, this is the fastest I have ever seen! I have had my lights for about 6 weeks now (new build, new rock) and most of the rock is showing growth. The top shelf is completely covered as I have been ramping up the intensity slowly over that time. I imagine I will be completely purple in another 6 weeks.

 

Laborator, I see you have a CAD Lights LEd fixture. Which one? I just got the 24" w/remote. Haven't set it up yet. Wondering what kind of critters you've had success with under it. I'm not sure how to gauge these LED fixtures yey, and want to make sure I stock appropriately.
