The 2 rocks on the top look somewhat cycled. You'd expect a darker color of the rocks that have been in the tank for 8 months. Coralline "skeleton" can remain even on dry rocks sometimes. GHA grows fast so doesn't have to mean it's been 8 months, some get it within weeks. You may also want to test your PO4 which will be a good indicator of how cycled your rocks are. I've never seen cycled rocks that looked that clean...well not since pictures of my dad's tank from a long time ago when they used to think that bleaching rocks was the way to keep the tank nice and clean :)
Dang it. I think I might have been lied to then. That's unfortunate
