More recently, Schlacher et al. examined growth rates of Acropora solitaryensis under 150W metal halide bulbs rated at 5.5K, 10K, 14K, and 20K color temperatures (Schlacher, 2007). After 3 months of grow-out, the overall growth rates under the different bulbs were quite distinct: 6.2 mg/day at 5.5K, 4.9 mg/day at 10K, 8.5 mg/day at 14K, and 10.9 mg/day at 20K.

Qui dice che sono stati sottoposti deei pezzi di Acropora solitaryensis sotto HQI di 150W a vari spettri di emissione.E riporta la crescita in milligrammi giornalieri.A 20K cresce di più.

Using a brown Pocillopora meandrina as a test case, coral coloration was visually assayed after exposure of this SPS to focused light from either blue, red, green, yellow, or ultraviolet LED's over a period of greater than 7 weeks. The coral section irradiated by the blue LED turned from brown to pink, whereas the other colored lights either had no effect, or promoted coral bleaching. This limited investigation led to some intriguing speculation about the connection between growth light and coral color, and it sets the stage for the more extensive studies described below.

Qui dice che sono stati sottoposti dei pezzi di Pocillopora meandrina alla luce di led UV,Blu,Verde,giallo e rosso.Solo il led blu ha provocato il viraggio di colore da marrone a rosa mentre il rosso addirittura provoca lo sbiancamento.
