I have never used a splash shield or glass lids on tanks with C/f lighting, and had them sitting right on top with no mounting legs. Never had a problem. I guess the main thing is make sure the fixture is mounted securely, and avoid splashing. Use a GFCI, and of course dont drop it in the tank (seems obvious, but Ive done it!) I think if I was going to use a shield I would use glass, because acrylic warps.
