Guppies in a refugium

[Joker]

IMO 12 hrs may have been to long especially dripping what was the SG before adding? did you confirm they were in 1.026 SG water?

The sg in the bag was 0 as they where in freshwater. After dripping for the 12 hrs the sg was at 1.026, temp 78.5, alk 9.1(same as my tank), also ran a air pump as well.
