veiwing corals flouresence

[PRTA79]

has any who went to meeting in marlboro figured out what spectrum light to use to view corals flouresnce?????

The speaker used a 450nm excitation filter, if I recall correctly.

He didn't say the exact wavelength of the filter he used, but from looking at the graphs he presented it was around 420-470nm... anyway, he did say that pretty much any light in that range would cause fluorescence in some corals or others, so it was a matter of experimenting. If you want to see what can be done without any special equipment, take a look at my thread in the Photography forum: http://216.235.242.50/forums/showthread.php?t=6937

try just looking at your tank under actinc with yellow saftey glasses. You don't get the full florescence effect but it looks pretty cool.
