shaw - me - i would take all the rock out and leave just corals in glass - bare bottom and eggcrate shelving. take the rock and put it in a bucket of salt water in the dark for a month "cook" and scrub occationally. your corals in the tank will be fine. any rock with corals that can't be removed would be placed in a quarentine tank and individualy scrubbed and joes juiced (hot KALK works too)
