What would you rather have for rock??

I used live rock from a fellow reefer (Marco Rock) for my DT. I had a minimal cycle, no cyano and very little other algae.

I used 100% dry rock for my frag tank. I had a long cycle, no cyano, but crazy (I mean completely covering the entire tank) amounts of hair algae that lasted 2 months.

I had the same experience when I set up my display tank with dry. It was brutal to deal with.
