Metalliske farver på koraller - Hvordan ??
: tors 28. jun 2012 11:53
Når man er ude ved forhandlere, samt enkelte private akvarister, så ser man af og til, extreme metalliske farvestærke koraller.
De fleste koraller kan være flotte og forholdsvis farverige, men når 1 stk ultra-grade-metallic-farve koral sættes ved siden af, blegner ALT ved siden af.
Hvordan H... opnår man disse metalliske, nærmest selvlysende farver ?
Har netop idag hentet 1 stk Goniopora, i skrig-metallic grøn ..... Og tænker ... Er de farvede på nogen måde ?
Jeg har fundet dette på nettet, og her forklares det jo at det der gør korallen endnu mere skrigende, er et beskyttende lag, mod solens UV stråler...
Er dette korrekt ?

Color Loss Of SPS Corals
Acropora (and SPS corals) lose color under less UV radiation, the nice colors that all reefers want is basically a sunscreen that protects the zooxanthellae algae that feed the coral through photosynthesis the "sunscreen" comes from mass amounts of UV radiation and light and this tells the zooxanthellae algae living within the corals tissue that it needs to protect itself from bleaching and then it becomes a bright color, When corals are exposed to a lesser amount of light the coral will become a more subdued color because the bright sunscreen is not necessary to protect the zooxanthellae algae from bleaching (or in some cases a different kalvin rating like 6K,10K,14K and 20K, usually the higher the kalvin rating the more colorful your SPS will be). For instance if an acropora is blue and purple in a tank lit by a 400 watt 20K metal halide light and then put in to a tank with a 150 watt 10K metal halide the color may be more subdued instantaneously or over time.
