Temperature change

[walkabout]

I'm trying to calculate the difference between temperature and specific gravity for my water change station should I be really concerned in what the temperature is between tank 77 degrees and say new water temp 86, I want to do 2-1/2 gallon a day , I will do this through the whole day each day

if you're doing it throughout the day, I would imagine it should be ok......
