I read on another site that someone who was a plumber had came home and didn't wash his hands then for some reason reached into the tank with all the resins and other chemicals on his hands. Apparently his whole tank crashed! Thats a lot of of time, patience and $ down the tubes for a little carelessness. Mistakes happen just the results of some suck more than others.
