Green Liverock Turning...Grey?

[admiralmcstabby]

So for a while most of my liverock was green/bright green...which is a phase I'm familiar with but I've noticed that now a lot of that is now turninga grey color.

All of my parameters are good, pH is a little low but working on it. I have plenty of filtration in this Biocube 32 (Icecap Nano skimmer,
InTank media basket with mech filtration, Purigen, Chemi-Pure and extra rubble for added bio filtration) light is a Kessil, InkBird temp controller...everyone seems healthy.

Curious if anyone had any idea what "stage" this may be or what is going on.

Just your tank maturing. The green was algae. As it goes away, your rock will turn grey and eventually start to get covered in coralline algae.
