    Do fluorescent light on aquariums give off UV rays? I heard from a couple aquarium companies that UV rays hurt their products. When I called Tetra about TSS and the UV affects they told me to leave my aquarium lights off for 48hrs. Is it true that fluorescent light give off UV?

    Fluorescent lamps do emit minute amounts of UV rays, but I doubt it would be enough to worry about. The National Electrical Manufacturer's Associate did a study on the amount of UV radiation admitted by fluorescent lamps, and stated the following:

    When companies in the aquarium industry say UV light can harm their medications/treatments/whatever, they're generally referring to dedicated UV sterilizers, not the incidental amount that comes from tank lighting. I can confirm that I have used TSS with great results while leaving my lighting on.
