Coraline question

A few years back when I bought most of my live rock it was covered in irridecent blue, irridesent green &dark purple corraline. Now the beautiful but much more common purple/pink corraline is taking over. How would I encourage the other stuff to come back? specific supplements? Lighting change or both?
Thank YOu

Have to have a seed source of the other types for it to show up.

This is only my experience and so I can't say that this is true in all cases, but when I used Instant Ocean I had very little of the pinkish purple coraline. I did have some maroonish coraline though. Then I switched to Reef Crystals and I began to grow the pinkish purple coraline in a big way. In my bare bottom seahorse tank I did not want that so I switched back to IO and it has receded. I can't really say that other coraline has replaced it but the seahorse tank is not lit as intensely as most reef tanks, nor do I supplement with trace elements. Maybe try a salt with less calcium.

That sounds like amazing corraline algae! Worth fighting for! If a lesser one encroaches, why not do what you'd do with with any other unwanted algae? Remove it. Choose your weapon and defend the irridecents!

Calcium input should also help, but also helps the pink stuff. Maybe look at the ones that are doing the best, and try to move others to similar conditions of light and current.

I'd love to see pics of this stuff!
