Adding a black light?

[moe]

Black lights give off a lot of UV radiation that is very bad for any photosynthetic organisms. Whatever you do, do not put black lights on your tank unless you want to kill your corals. Like others said above try the powerbrite LED, they seem to give off a really strong blue light which will make your flourescent colors pop more.

good to know thanks for that info. i knew about the UV but i didn't know how it would affect the the corals. And now I know so i won't be putting one up.

when i first started in this hobby, i added a NO fluorescent black light that i had on for an hour or two every night. within a week, all of the corals (gsp and other softies) refused to open whether or not the light was on. after a couple of weeks without it, most of them recovered. dont know for sure if it was the black light, but it sure seemed like it.

Did the coral skeletons glow Ace? LOL!

Skip the black light and get some actinic supplementation.

I use the BLUE several hours before lights on and several hours after lights off.

LOVE THEM! Colors pop like you would not believe!
