Changing the rocks in my tank

[Kmore1219]

hey everyone so it looks like I've got bryopis and some other algaes growing in my tank that I just can't get rid of. I was thinking of just removing the rock and somewhat restarting my tank, is there a good way I should go about this or even another method to maybe save my tank? I've got quite a few corals but it looks like only my zoas are doing good, as for fish it's only my clowns.

Can you post some photos of the nuisance algae so we can get a better idea of what you're fighting here?
