What I use to acclimate fish I want to make sure the temperature in the bucket is the same as in the aquarium. These little heaters are great because they keep the temperature in the tank and then I can adjust it appropriately and pop it in the bucket when the salinity and pH match. The actual heater calibration is irrelevant, just a number.
