Things You'll Need
- Bleach
- 2 large containers
Instructions
Place the coral in a container of cold, fresh water for three days. This will remove any sea life that is living inside the coral, along with removing dirt, debris and salt.
Fill a large container with two parts bleach and one part water. You want enough to cover the coral completely.
Soak the coral in the bleach mixture for 48 hours, then rinse thoroughly with cold water.
