yes, you can use dry rock and let it slowly seed into LR. i would still soak and rinse the dry rock to clean out crud that always seems to get into them.

 

tufa and lava (red) rocks are most commonly used but throwaway LR is another good option. many lfs will have loose/used rock bins to cherry pick over at a fraction of the cost of their LR.

 

for the used/nuked rock i always additionally cycle in a separate container (usually a bucket) with poly-filters, just in case they were from a copper-medicated FOWLR. hth

i went from a mb7 to a 10. i just bought a couple extra pounds of live rock. just go to a LFS you can trust and make sure you get fully cured LR.
