You can use the hyposalinity method or the copper method.
Hypo involves slowly lowering the salinity of the water.
If you use copper you will have to dose certain amounts of it and test to make sure you are not adding too much or too little at a given time.
Both methods will kill bacteria, corals, and inverts so the methods work best when being executed in a quarantine tank setup.
