Uv spectrum for Sps coloration

[ahmedess]

I ve been reading about the colorful protective pigments that sps produce to protect itself from radiation and i am interested in buying some uv leds to make my sps get more colorful since i m using no Mh lamps and i have no source of uv at the moment. The problem is that there are several uv leds around with different wavelengths and i really dont know which wavelengths to get.
