Yes I did acclimate but not as well as I would have liked. The fatheads were in a normal clear bag and didn't lose their oxygen so they were easy. The BG looked in bad shape so I guess I may have made a bad decision I poured some pond water in the bag but it didn't seem to help, so I floated the cooler and all out into the pond and let the bags float out of the cooler while I held the top of the bags. This allowed the pond water to push the air out of the bag so the BG were sandwich between 2 plastic walls. One bad decision after another starting with the fish guys using the trash bags. I'm not looking to put the blame on them, I just want to correct any issues that I may have to my stocking plan. They will be in the area again June 18th. I have no problem buying more fish if need be. Can I have too many? These are forage in a new pond before I add LMB and HSB next year.
