What is the difference between pre-cured and un-cured live rock?
The main difference between pre-cured live rock and uncured live rock is how they are handled once they have been collected. Pre-cured live rock is rock kept in special holding areas and sprayed with a constant mist of seawater. The spray drives out unwanted species such as bristle worms and mantis shrimp and dislodges loose organic debris. Uncured live rock is rock that has not been through this process. For this reason, uncured live rock tends to have a greater, initial biodiversity.
