vic 21 this is the same as my original acclimation method except:
the problem i had with it still applies- unless your room temp is within a couple of degrees of your tank, sensitive species will be stressed unless the container is in the tank or heated by it's own independent heater.
lunch box- your method is about the same as mine but i get fed up with opening and closing the bag and holding it open to remove and add water- container makes life a lot easier----especially is you get one that fits snuggly between your your hood and the tankside just under the access "door".
