Water CLoudy Under BlackLight?

Yeah, that's what happens with black light. Are you looking for a scientific explanation of why this is, or just if that's normal?
Well, black light emits ultraviolet radiation. UV radiation falls outside of the visible range on the color spectrum...it is invisible except for the effect it has on something called phosphors. Phosphors absorb radiation and use that energy to emit visible light. Different phosphors produce different colors. My guess is that your water has phosphates and possibly other dissolved organic compounds which are absorbing the UV radiation.
I know jellyfish tanks in public aquariums use black light, but that water is probably spotlessly clean and pure from the sheer volume of it...how big is your tank? Is it one of those little kit type things Tetra makes? Like a 3-5 gallon plastic thing? Because if so then the water is probably polluted, even if it looks clear to your eye.

Hmm, sorry if I'm wrong then...was just a guess! Chris K, do you know why the "dirty water" clouds as opposed to clean water right out of the tap?
Sorry Born, I just assumed it was one of those kit things with the black light, and they are always ridiculously small and cheap. I take it you got a fluorescent black light bulb right? I only ever found those at places like Spencer's, kinda hard to find at least in my neck of the woods.
Of course, the night clubs have to get them from somewhere right...?

Lowes sells blacklights- they may have the bulbs too. Organics in general glow under blacklight- just think of a hotel room bed. Or shine it on the drool spot on your pillow, not to mention so many other elephant in the room things. What your seeing is various wastes- Dissolved Solids. Your tap water has little to none- where as the water is your tank, with living orgainisms producing waste does.
And as a suggestion for seeing your glo-fish- get some blue led's, or a blue cold cathode tube- DIY moonlight mod style- you'll see the glow fish, your florcent decorations if any will glow, and you're water won't look so cloudy. Glo-fish look a lot cooler under blue light than they do under black.
