190g tank

So I have a 29gal reef tank for prob 2 years, tank is deff established. I’m planning on buying a 190 72x26x24 display making it mixed reef. If i put the rock from my tank now in the new display or even the sump, will that prevent the ugly phase or algae boom? Or is there no way around that
