| It is not known whether rugose corals had symbiotic photosymbiotic zooxanthellae as modern corals do. |
| It is possible to reduce the amount of zooxanthellae so much that the coral will not get enough energy via photosynthesis. |
| It is possible with this product to influence the amount of zooxanthellae in the coral tissue. |
| This food source does not increase the zooxanthellae reproduction even if overdosed. |
| The coral itself has more energy for growth because the zooxanthellae density requires less energy. |
| The reduction of zooxanthellae occurs within 48 hours and also reaches its highest point at that time. |
