I was really excited to clear up some space in the tool shed by moving my Leslie's Power Powder Pro Chlorine container over by the pool pump, in the sun for the last half of the day. My excitement was squashed when my Leslie's tech told me that the stuff is sensitive to heat and storing out in the sun is a bad bad idea. This is a popular commercial product that I swear I have seen the red top in pool trucks driving around all day in the 100 degree Texas heat. He seemed to express the fear of an explosion or fire due to heat and combustion.... Does anyone have any thoughts on this?
