I really don't see that killing every single fish I have never done anything but float the bag and I have never lost a fish due to an acclamation problem. I think they are being suffocated because of the top on the tank.Thats what I mean. If the salinity is off by enough its the only thing it could be.Swdummie already stated she only temp acclimated. If she truely is at 1.024 and not off. Then 1.019-1.020 at the lfs could be too big of a jump. When I order fish they come in at 1.017!
Do you have a sump or no? Just curiousI have tops on my tanks
