You can situate the crushed coral into the rock work like it might lay naturally. The bacteria will be water born and will find purchase within the porous base rock. This will happen over weeks and months as the bacteria multiplies. Since there should be no die off, I would not expect your tank to have a hard cycle. The purple up isn't a bad idea, but as said elsewhere, if it is coralline algae you are after, it is about calcium and alkalinity levels. Slow and stable is what you want your reef to be. Nothing happening fast, except coral growth and even that on its best day is pretty slow. Think carefully every time you dose the tank with anything except a good water change. Read what is in purple up. Same with B-Ionic, BSR sells the same basic supplement in a kit form. You will see that old time aquarists and public aquarium managers use targeted chemicals that can be tested for when maintaining a closed reef system. BRS is very good in making those pure chemicals available with easy to follow instructions.
