Galvanized wire (at least PROPERLY galvanized wire :-) is dipped in molten
zinc. The zinc will gradually come off into the water column if left
submersed. I don't think you would see any harm from a little bit in the
tank, but I personally wouldn't try it. You are much better off using a
piece of plastic gutter guard (which is normally polyethelene) or some
fiberglass (plastic) window screen. Either can be purchased for very little
money in most hardware stoors.
