this is an every summer occurance, heat waves come and people report loss. the best way to prevent summer RTN is to buy a chiller. I used to swing feom 78 to 85 all the time with no problems but when I started getting up to 88/89 then I would have problems, and at 104 you lose your whole tank
My chiller kept the temp swing to 2 degrees all year and no more problems
