how much rock to cycle a new tank?

plus 1 and I would add.

IMO, It is a good idea to take a scoop of your old sand near the edge where you see the worms.
The reason is the critters that live in the rock are not the same critters that live in the sand so the scoop will start a new population of sand critters.

im gonna hop in here, i had 45g 90g and a 60g i added all the livestock, sand, coral, and rock to one big 160g.
anonia has been .25 , 0 nitrite and 0 nirate
im pretty sure im going to kill everything.
i have been using prime to keep the amonia down.
so far so good fish are happy and eating.
i had to do a 50% water change, but now im worried.

Suck out all that old dirty sand with a siphon hose, and wash it really well. Add it back in in a month or so once you're done cleaning it up. That's what I would do.
