Black egg crate is the preferred surface for mounting large numbers of coral frags for the following reasons:
- Securely holds a large quantity of coral frags in the smallest area.
- All black color is less likely to attract plague algae growth.
- All black color is attractive in the tank and in photos.
- 100% reef safe
