Eric,
take a look at the picture before you see the timers. I made a wooden fixture behind the tank to house/hide all the electricity, timers and drip bags. I made the box front purposely lower than the tank top to stop any splashing/dripping from the tank. The timers are boxed in, I attached hinges to the box to allow me to make any necessary adjustments. Do you think that this fixture sufficiently address's your concerns? I haven't had any spillage or salt creep yet.
