Reviving an old thread... I have about 20 lbs dead rock from my tank crash, which has been dried indoors for almost 3 years. I want to reintroduce into my established reef, but I know there is probably a lot of dead stuff and phosphates in it. Recommend long cure with fresh salt water changes, powerhead, heater with water changes, or bleach, or muratic acid? I'm assuming muratic acid is the most effective and fastest. Do I still need to cure after acid bath, or just reintroduce after several good rinses?
