Hi all, I just dug out an old lighting fixture that I've used on freshwater tanks over the years. I cleaned it up hoping to use it on my covered FOWLR tank, and in the process of cleaning I saw a little label that says it's for freshwater use only. Why would that be the case? I'm having difficulty seeing see how a hard plastic fixture that's protected from the water by a glass hood (the fixture and hood types were actually sold together) would experience problems with saltwater vs. freshwater. In both cases there would be no way for water to splash up and hit the light directly, since there's a glass pane in the way. The tank gets some salt deposits around the rim, but not near where the fixture would sit. Is the freshwater-only assertion likely to be bogus, or is there some serious reason I'm missing that would cause a light fixture to have that sort of label on it, given that it's already intended to be used with a covered-top tank?
