How to Bleach Coral

Coral are multi-colored plants that give character to your aquarium. Like rocks and other decorative accessories, coral becomes dirty over time and grime builds up on its surfaces. Coral is also susceptible to discoloration feces, food particles and debris from fish and sea life you have in the aquarium. A bleach solution safely cleans coral. Once clean, rinse the coral thoroughly to remove any bleach solution and lingering residue.

Things You'll Need

Large plastic container or bowl
Cold water
Non-fragrance chlorine bleach
Dechlorinating solution
Old towel
