When you do water changes, do you expose the tops of those rocks to air for any period of time? I find coraline algae often turns white after being exposed to air for 5+ minutes.
Aside from that, not sure what to suggest. The lighting you have shouldnt' washout your rocks.
Maybe use kalk water for topups and get the coraline algae growing more on the rocks.

It just doesn't have any algae or coralline on it thats all. Coralline likes dimmer light. You could reduce your photoperiod but to me it just looks like you need to attach a coral frag there

ya I got some sections of my rock like that. Cover them with light loving coral's

I sake dwhat critters you have because since I added my urchin he has eaten some of my coriline algae, in one spot it looks like your rock just a smaller area. your herms could do the same thing. But I would just put a coral there and it will clear up.
