I use drip acclimation for fish and invert. I will float the bag for 45 min then normally only drip for 30 min.
For me I focus on the drip rate, for fish water must increase at least 70%, invert is 100%.
Temp different wise, I think is ok unless got different by > 1 degree
If u don't do acclimation then u fish will shock if ur PH and SG is different from the LFS.
