    Buy it from LFS, called bio-rock, works pretty well to make up volume of the reef

    Depends what it's made of. You want a porous rock, to allow bacteria to grow deep inside the rock.

    Granite won't do it. Sandstone will be good. Coral skeletons even better.

    Why not making your own using crushed coral and portland cement? You add some coarse salt before moulding it to make it more porous. You could make a lot quite cheap!

    Gershwin - to DIY your own rock:
    - white cement
    - aragonite
    - rough sea salt
    Mix these in equal quantities, and mix with very little water, that you have a dry'ish cement mix.... it must be much more like clay...

    I would understand washing and rinsing but curing is normally associated with cycling your rock's dead organisms and basically making sure you don't have an algae bloom or ammonia spike
