You mean of course 9.00 on the DKH?
Yes, your rock is and will be constant changing color, of course when your tank is established a lot less but I would enjoy the ride.
Any pictures of your tank?

Sounds like a typical break in salt tank! Watch it and learn, many amazing things happen in these early stages.

It's just the coralline growing and competeting with each other.... More blue to white light yields pink and purple coralline

Duller ligjts will grow green and brown versions

My rocks have green and brown coralline growing on the mid to bottom and pink coralline growing on the tops it's perfectly normal
