Could have been a higher PH if yours was 8.3 for example and the lfs
was 7.8 with only an hour to adjust. That's why they need the longer drip acclimation for both PH and SG
adjustment to keep from going into osmotic shock and dieing.
As long as your nh3
is 0 ppm
below 20 ppm
there is no harm in getting another right away. Just make sure you drip for 2-3 hours and it should be fine. Also IME it's best not to expose them to air and I transfer with a plastic cup.
Keep in mind that about 80% of the time shrimp will molt within the first 3-5 days when introduced to a tank with lr
because often they are in the open at the lfs
and do not like to do it unless they have to.
Shrimp are slightly more vulnerable with a soft shell after molting so as long as you don't have any aggressive fish that could take advantage of it till it's shell hardens (3-5 days) then it should do just fine.
