    Are you sure it is liverock and not some other thing.
    You would have to cure it first.

    So first bleach it then care it.

    even though its dead now and you could leach and spike readings etc etc what worries me is that after all these YEARS what could be living in them that you cannot get out ,especially if its porous..... dead in a sealed bucket for years now thats different,but plenty of um.. very non reef safe things in the garden..

    It could be used but it would be a huge effort to get all that stuff out. Lots of bleaching, disinfecting and curing could take a while...

    It looks like fossilized coral reef and for now I put it in water with 15% CL solution

    I am using base rock and and dead live rock that was in the garden. The process is exactly the same as curing live rock. After its been bleached it just needs to cycle so all the dead gets eaten. It might leach phosphates, just cycle for longer under lights. Algae will grow and eat phosphates. Or use a phosphate remover.

    I would be cautious though if chemicals or poison has been used in the garden.

    Hi @oliver as far as Im aware the only poison that has been in commercial use that does not break down in a few weeks is DDT, The majority of commercially available garden poisons are phosphate or carbamide based, they brake down into harmless substinces quite quickly, anyway if I was you I would cycle the rock in a seperate container or drum and after about 6 weeks do the normal tests as in p04 n02 n03 and then decide what you want to do from there .Me personnally I would make my choice once the cycle is complete and you are seeing new life and growth on the rocks.

    I would cycle the rock in a separate tub for 6 weeks. Rinse them often. Lift and shake about to get rid of all the sand and dirt that went into it over the years.
